By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission.

These conventions are necessary, in part, for separate +compilation to work. One such convention is the "calling +convention". The "calling convention" is essentially a set of +assumptions made by the compiler about where function arguments will +be found on entry to a function. A "calling convention" also specifies +where the return value for a function is found. + +Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call +a given function. Libffi can be used in such programs to provide a +bridge from the interpreter program to compiled code. + +The libffi library provides a portable, high level programming +interface to various calling conventions. This allows a programmer to +call any function specified by a call interface description at run +time. + +FFI stands for Foreign Function Interface. A foreign function +interface is the popular name for the interface that allows code +written in one language to call code written in another language. The +libffi library really only provides the lowest, machine dependent +layer of a fully featured foreign function interface. A layer must +exist above libffi that handles type conversions for values passed +between the two languages. + + +Supported Platforms +=================== + +Libffi has been ported to many different platforms. + +At the time of release, the following basic configurations have been +tested: + +| Architecture | Operating System | Compiler | +| --------------- | ---------------- | ----------------------- | +| AArch64 (ARM64) | iOS | Clang | +| AArch64 | Linux | GCC | +| AArch64 | Windows | MSVC | +| Alpha | Linux | GCC | +| Alpha | Tru64 | GCC | +| ARC | Linux | GCC | +| ARC32 | Linux | GCC | +| ARC64 | Linux | GCC | +| ARM | Linux | GCC | +| ARM | iOS | GCC | +| ARM | Windows | MSVC | +| AVR32 | Linux | GCC | +| Blackfin | uClinux | GCC | +| CSKY | Linux | GCC | +| HPPA | HPUX | GCC | +| HPPA64 | HPUX | GCC | +| KVX | Linux | GCC | +| IA-64 | Linux | GCC | +| LoongArch64 | Linux | GCC | +| M68K | FreeMiNT | GCC | +| M68K | Linux | GCC | +| M68K | RTEMS | GCC | +| M88K | OpenBSD/mvme88k | GCC | +| Meta | Linux | GCC | +| MicroBlaze | Linux | GCC | +| MIPS | IRIX | GCC | +| MIPS | Linux | GCC | +| MIPS | RTEMS | GCC | +| MIPS64 | Linux | GCC | +| Moxie | Bare metal | GCC | +| OpenRISC | Linux | GCC | +| PowerPC 32-bit | AIX | GCC | +| PowerPC 32-bit | AIX | IBM XL C | +| PowerPC 64-bit | AIX | IBM XL C | +| PowerPC | AMIGA | GCC | +| PowerPC | Linux | GCC | +| PowerPC | Mac OSX | GCC | +| PowerPC | FreeBSD | GCC | +| PowerPC 64-bit | FreeBSD | GCC | +| PowerPC 64-bit | Linux ELFv1 | GCC | +| PowerPC 64-bit | Linux ELFv2 | GCC | +| RISC-V 32-bit | Linux | GCC | +| RISC-V 64-bit | Linux | GCC | +| S390 | Linux | GCC | +| S390X | Linux | GCC | +| SH3 | Linux | GCC | +| SH4 | Linux | GCC | +| SH5/SH64 | Linux | GCC | +| SPARC | Linux | GCC | +| SPARC | Solaris | GCC | +| SPARC | Solaris | Oracle Solaris Studio C | +| SPARC64 | Linux | GCC | +| SPARC64 | FreeBSD | GCC | +| SPARC64 | Solaris | Oracle Solaris Studio C | +| TILE-Gx/TILEPro | Linux | GCC | +| VAX | OpenBSD/vax | GCC | +| WASM32 | Emscripten | EMCC | +| WASM64 | Emscripten | EMCC | +| X86 | FreeBSD | GCC | +| X86 | GNU HURD | GCC | +| X86 | Interix | GCC | +| X86 | kFreeBSD | GCC | +| X86 | Linux | GCC | +| X86 | OpenBSD | GCC | +| X86 | OS/2 | GCC | +| X86 | Solaris | GCC | +| X86 | Solaris | Oracle Solaris Studio C | +| X86 | Windows/Cygwin | GCC | +| X86 | Windows/MinGW | GCC | +| X86-64 | DragonFly BSD | GCC | +| X86-64 | FreeBSD | GCC | +| X86-64 | Linux | GCC | +| X86-64 | Linux/x32 | GCC | +| X86-64 | OpenBSD | GCC | +| X86-64 | Solaris | Oracle Solaris Studio C | +| X86-64 | Windows/Cygwin | GCC | +| X86-64 | Windows/MinGW | GCC | +| X86-64 | Mac OSX | GCC | +| Xtensa | Linux | GCC | + +Please send additional platform test results to +libffi-discuss@sourceware.org. + +Installing libffi +================= + +First you must configure the distribution for your particular +system. Go to the directory you wish to build libffi in and run the +"configure" program found in the root directory of the libffi source +distribution. Note that building libffi requires a C99 compatible +compiler. + +If you're building libffi directly from git hosted sources, configure +won't exist yet; run ./autogen.sh first. This will require that you +install autoconf, automake, libtool and texinfo. + +You may want to tell configure where to install the libffi library and +header files. To do that, use the ``--prefix`` configure switch. Libffi +will install under /usr/local by default. + +If you want to enable extra run-time debugging checks use the the +``--enable-debug`` configure switch. This is useful when your program dies +mysteriously while using libffi. + +Another useful configure switch is ``--enable-purify-safety``. Using this +will add some extra code which will suppress certain warnings when you +are using Purify with libffi. Only use this switch when using +Purify, as it will slow down the library. + +If you don't want to build documentation, use the ``--disable-docs`` +configure switch. + +It's also possible to build libffi on Windows platforms with +Microsoft's Visual C++ compiler. In this case, use the msvcc.sh +wrapper script during configuration like so: + + path/to/configure CC=path/to/msvcc.sh CXX=path/to/msvcc.sh LD=link CPP="cl -nologo -EP" CXXCPP="cl -nologo -EP" CPPFLAGS="-DFFI_BUILDING_DLL" + +For 64-bit Windows builds, use ``CC="path/to/msvcc.sh -m64"`` and +``CXX="path/to/msvcc.sh -m64"``. You may also need to specify +``--build`` appropriately. + +It is also possible to build libffi on Windows platforms with the LLVM +project's clang-cl compiler, like below: + + path/to/configure CC="path/to/msvcc.sh -clang-cl" CXX="path/to/msvcc.sh -clang-cl" LD=link CPP="clang-cl -EP" + +When building with MSVC under a MingW environment, you may need to +remove the line in configure that sets 'fix_srcfile_path' to a 'cygpath' +command. ('cygpath' is not present in MingW, and is not required when +using MingW-style paths.) + +To build static library for ARM64 with MSVC using visual studio solution, msvc_build folder have + aarch64/Ffi_staticLib.sln + required header files in aarch64/aarch64_include/ + + +SPARC Solaris builds require the use of the GNU assembler and linker. +Point ``AS`` and ``LD`` environment variables at those tool prior to +configuration. + +For iOS builds, the ``libffi.xcodeproj`` Xcode project is available. + +Configure has many other options. Use ``configure --help`` to see them all. + +Once configure has finished, type "make". Note that you must be using +GNU make. You can ftp GNU make from ftp.gnu.org:/pub/gnu/make . + +To ensure that libffi is working as advertised, type "make check". +This will require that you have DejaGNU installed. + +To install the library and header files, type ``make install``. + + +History +======= + +See the git log for details at http://github.com/libffi/libffi. + + 3.5.2 Aug-2-2025 + Add wasm64 support. + Add DragonFly BSD

These conventions are necessary, in part, for separate +compilation to work. One such convention is the @dfn{calling +convention}. The calling convention is a set of assumptions made by +the compiler about where function arguments will be found on entry to +a function. A calling convention also specifies where the return +value for a function is found. The calling convention is also +sometimes called the @dfn{ABI} or @dfn{Application Binary Interface}. +@cindex calling convention +@cindex ABI +@cindex Application Binary Interface + +Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call +a given function. @code{libffi} can be used in such programs to +provide a bridge from the interpreter program to compiled code. + +The @code{libffi} library provides a portable, high level programming +interface to various calling conventions. This allows a programmer to +call any function specified by a call interface description at run +time. + +@acronym{FFI} stands for Foreign Function Interface. A foreign +function interface is the popular name for the interface that allows +code written in one language to call code written in another language. +The @code{libffi} library really only provides the lowest, machine +dependent layer of a fully featured foreign function interface. A +layer must exist above @code{libffi} that handles type conversions for +values passed between the two languages. +@cindex FFI +@cindex Foreign Function Interface + + +@node Using libffi +@chapter Using libffi + +@menu +* The Basics:: The basic libffi API. +* Simple Example:: A simple example. +* Types:: libffi type descriptions. +* Multiple ABIs:: Different passing styles on one platform. +* The Closure API:: Writing a generic function. +* Closure Example:: A closure example. +* Thread Safety:: Thread safety. +@end menu + + +@node The Basics +@section The Basics + +@code{libffi} assumes that you have a pointer to the function you wish +to call and that you know the number and types of arguments to pass +it, as well as the return type of the function. + +The first thing you must do is create an @code{ffi_cif} object that +matches the signature of the function you wish to call. This is a +separate step because it is common to make multiple calls using a +single @code{ffi_cif}. The @dfn{cif} in @code{ffi_cif} stands for +Call InterFace. To prepare a call interface object, use the function +@code{ffi_prep_cif}. +@cindex cif + +@findex ffi_prep_cif +@defun ffi_status ffi_prep_cif (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes}) +This initializes @var{cif} according to the given parameters. + +@var{abi} is the ABI to use; normally @code{FFI_DEFAULT_ABI} is what +you want. @ref{Multiple ABIs} for more information. + +@var{nargs} is the number of arguments that this function accepts. + +@var{rtype} is a pointer to an @code{ffi_type} structure that +describes the return type of the function. @xref{Types}. + +@var{argtypes} is a vector of @code{ffi_type} pointers. +@var{argtypes} must have @var{nargs} elements. If @var{nargs} is 0, +this argument is ignored. + +@code{ffi_prep_cif} returns a @code{libffi} status code, of type +@code{ffi_status}. This will be either @code{FFI_OK} if everything +worked properly; @code{FFI_BAD_TYPEDEF} if one of the @code{ffi_type} +objects is incorrect; or @code{FFI_BAD_ABI} if the @var{abi} parameter +is invalid. +@end defun + +If the function being called is variadic (varargs) then +@code{ffi_prep_cif_var} must be used instead of @code{ffi_prep_cif}. + +@findex ffi_prep_cif_var +@defun ffi_status ffi_prep_cif_var (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nfixedargs}, unsigned int @var{ntotalargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes}) +This initializes @var{cif} according to the given parameters for +a call to a variadic function. In general its operation is the +same as for @code{ffi_prep_cif} except that: + +@var{nfixedargs} is the number of fixed arguments, prior to any +variadic arguments. It must be greater than zero. + +@var{ntotalargs} the total number of arguments, including variadic +and fixed arguments. @var{argtypes} must have this many elements. + +@code{ffi_prep_cif_var} will return @code{FFI_BAD_ARGTYPE} if any of +the variable argument types are @code{ffi_type_float} (promote to +@code{ffi_type_double} first), or any integer type small than an int +(promote to an int-sized type first). + +Note that, different cif's must be prepped for calls to the same +function when different numbers of arguments are passed. + +Also note that a call to @code{ffi_prep_cif_var} with +@var{nfixedargs}=@var{nototalargs} is NOT equivalent to a call to +@code{ffi_prep_cif}. + +@end defun + +Note that the resulting @code{ffi_cif} holds pointers to all the +@code{ffi_type} objects that were used during initialization. You +must ensure that these type objects have a lifetime at least as long +as that of the @code{ffi_cif}. + +To call a function using an initialized @code{ffi_cif}, use the +@code{ffi_call} function: + +@findex ffi_call +@defun void ffi_call (ffi_cif *@var{cif}, void *@var{fn}, void *@var{rvalue}, void **@var{avalues}) +This calls the function @var{fn} according to the description given in +@var{cif}. @var{cif} must have already been prepared using +@code{ffi_prep_cif}. + +@var{rvalue} is a pointer to a chunk of memory that will hold the +result of the function call. This must be large enough to hold the +result, no smaller than the system register size (generally 32 or 64 +bits), and must be suitably aligned; it is the caller's responsibility +to ensure this. If @var{cif} declares that the function returns +@code{void} (using @code{ffi_type_void}), then @var{rvalue} is +ignored. + +In most situations, @code{libffi} will handle promotion according to +the ABI. However, for historical reasons, there is a special case +with return values that must be handled by your code. In particular, +for integral (not @code{struct}) types that are narrower than the +system register size, the return value will be widened by +@code{libffi}. @code{libffi} provides a type, @code{ffi_arg}, that +can be used as the return type. For example, if the CIF was defined +with a return type of @code{char}, @code{libffi} will try to store a +full @code{ffi_arg} into the return value. + +@var{avalues} is a vector of @code{void *} pointers that point to the +memory locations holding the argument values for a call. If @var{cif} +declares that the function has no arguments (i.e., @var{nargs} was 0), +then @var{avalues} is ignored. + +Note that while the return value must be register-sized, arguments +should exactly match their declared type. For example, if an argument +is a @code{short}, then the entry in @var{avalues} should point to an +object declared as @code{short}; but if the return type is +@code{short}, then @var{rvalue} should point to an object declared as +a larger type -- usually @code{ffi_arg}. +@end defun + +@findex ffi_get_version +@defun {const char *} ffi_get_version (void) +Returns the library version as a string. This string is also +available at build time as the macro @code{FFI_VERSION_STRING}. +@end defun + +@findex ffi_get_version_number +@defun {unsigned long} ffi_get_version_number (void) +Returns the library version as an unsigned long value where +version ``x.y.z'' is represented as the number x*10000+y*100+z. +This number is also available at build time as the macro +@code{FFI_VERSION_NUMBER}. +@end defun + +@findex ffi_get_default_abi +@defun {unsigned int} ffi_get_default_abi (void) +Return the value of @code{FFI_DEFAULT_ABI}. +@end defun + +@findex ffi_get_closure_size +@defun {size_t} ffi_get_closure_size (void) +Return @code{sizeof(ffi_closure)}. +@end defun + +@node Simple Example +@section Simple Example + +Here is a trivial example that calls @code{puts} a few times. + +@example +#include +#include + +int main() +@{ + ffi_cif cif; + ffi_type *args[1]; + void *values[1]; + char *s; + ffi_arg rc; + + /* Initialize the argument info vectors */ + args[0] = &ffi_type_pointer; + values[0] = &s; + + /* Initialize the cif */ + if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ffi_type_sint, args) == FFI_OK) + @{ + s = "Hello World!"; + ffi_call(&cif, (void(*)())puts, &rc, values); + /* rc now holds the result of the call to puts */ + + /* values holds a pointer to the function's arg, so to + call puts() again all we need to do is change the + value of s */ + s = "This is cool!"; + ffi_call(&cif, (void(*)())puts, &rc, values); + @} + + return 0; +@} +@end example + + +@node Types +@section Types + +@menu +* Primitive Types:: Built-in types. +* Structures:: Structure types. +* Size and Alignment:: Size and alignment of types. +* Arrays Unions Enums:: Arrays, unions, and enumerations. +* Type Example:: Structure type example. +* Complex:: Complex types. +* Complex Type Example:: Complex type example. +@end menu + +@node Primitive Types +@subsection Primitive Types + +@code{Libffi} provides a number of built-in type descriptors that can +be used to describe argument and return types: + +@table @code +@item ffi_type_void +@tindex ffi_type_void +The type @code{void}.

However, there are some caveats. + +@itemize @bullet +@item +The size or alignment of some of the built-in types may vary depending +on the chosen ABI. + +@item +The size and alignment of a new structure type will not be set by +@code{libffi} until it has been passed to @code{ffi_prep_cif} or +@code{ffi_get_struct_offsets}. + +@item +A structure type cannot be shared across ABIs. Instead each ABI needs +its own copy of the structure type. +@end itemize + +So, before examining these fields, it is safest to pass the +@code{ffi_type} object to @code{ffi_prep_cif} or +@code{ffi_get_struct_offsets} first. This function will do all the +needed setup. + +@example +ffi_type *desired_type; +ffi_abi desired_abi; +@dots{} +ffi_cif cif; +if (ffi_prep_cif (&cif, desired_abi, 0, desired_type, NULL) == FFI_OK) + @{ + size_t size = desired_type->size; + unsigned short alignment = desired_type->alignment; + @} +@end example + +@code{libffi} also provides a way to get the offsets of the members of +a structure. + +@findex ffi_get_struct_offsets +@defun ffi_status ffi_get_struct_offsets (ffi_abi abi, ffi_type *struct_type, size_t *offsets) +Compute the offset of each element of the given structure type. +@var{abi} is the ABI to use; this is needed because in some cases the +layout depends on the ABI. + +@var{offsets} is an out parameter. The caller is responsible for +providing enough space for all the results to be written -- one +element per element type in @var{struct_type}. If @var{offsets} is +@code{NULL}, then the type will be laid out but not otherwise +modified. This can be useful for accessing the type's size or layout, +as mentioned above. + +This function returns @code{FFI_OK} on success; @code{FFI_BAD_ABI} if +@var{abi} is invalid; or @code{FFI_BAD_TYPEDEF} if @var{struct_type} +is invalid in some way. Note that only @code{FFI_STRUCT} types are +valid here. +@end defun + +@node Arrays Unions Enums +@subsection Arrays, Unions, and Enumerations + +@subsubsection Arrays + +@code{libffi} does not have direct support for arrays or unions. +However, they can be emulated using structures. + +To emulate an array, simply create an @code{ffi_type} using +@code{FFI_TYPE_STRUCT} with as many members as there are elements in +the array. + +@example +ffi_type array_type; +ffi_type **elements +int i; + +elements = malloc ((n + 1) * sizeof (ffi_type *)); +for (i = 0; i < n; ++i) + elements[i] = array_element_type; +elements[n] = NULL; + +array_type.size = array_type.alignment = 0; +array_type.type = FFI_TYPE_STRUCT; +array_type.elements = elements; +@end example + +Note that arrays cannot be passed or returned by value in C -- +structure types created like this should only be used to refer to +members of real @code{FFI_TYPE_STRUCT} objects. + +However, a phony array type like this will not cause any errors from +@code{libffi} if you use it as an argument or return type. This may +be confusing. + +@subsubsection Unions + +A union can also be emulated using @code{FFI_TYPE_STRUCT}. In this +case, however, you must make sure that the size and alignment match +the real requirements of the union. + +One simple way to do this is to ensue that each element type is laid +out. Then, give the new structure type a single element; the size of +the largest element; and the largest alignment seen as well. + +This example uses the @code{ffi_prep_cif} trick to ensure that each +element type is laid out. + +@example +ffi_abi desired_abi; +ffi_type union_type; +ffi_type **union_elements; + +int i; +ffi_type element_types[2]; + +element_types[1] = NULL; + +union_type.size = union_type.alignment = 0; +union_type.type = FFI_TYPE_STRUCT; +union_type.elements = element_types; + +for (i = 0; union_elements[i]; ++i) + @{ + ffi_cif cif; + if (ffi_prep_cif (&cif, desired_abi, 0, union_elements[i], NULL) == FFI_OK) + @{ + if (union_elements[i]->size > union_type.size) + @{ + union_type.size = union_elements[i]; + size = union_elements[i]->size; + @} + if (union_elements[i]->alignment > union_type.alignment) + union_type.alignment = union_elements[i]->alignment; + @} + @} +@end example + +@subsubsection Enumerations + +@code{libffi} does not have any special support for C @code{enum}s. +Although any given @code{enum} is implemented using a specific +underlying integral type, exactly which type will be used cannot be +determined by @code{libffi} -- it may depend on the values in the +enumeration or on compiler flags such as @option{-fshort-enums}. +@xref{Structures unions enumerations and bit-fields implementation, , , gcc}, +for more information about how GCC handles enumerations. + +@node Type Example +@subsection Type Example + +The following example initializes a @code{ffi_type} object +representing the @code{tm} struct from Linux's @file{time.h}. + +Here is how the struct is defined: + +@example +struct tm @{ + int tm_sec; + int tm_min; + int tm_hour; + int tm_mday; + int tm_mon; + int tm_year; + int tm_wday; + int tm_yday; + int tm_isdst; + /* Those are for future use. */ + long int __tm_gmtoff__; + __const char *__tm_zone__; +@}; +@end example + +Here is the corresponding code to describe this struct to +@code{libffi}: + +@example + @{ + ffi_type tm_type; + ffi_type *tm_type_elements[12]; + int i; + + tm_type.size = tm_type.alignment = 0; + tm_type.type = FFI_TYPE_STRUCT; + tm_type.elements = tm_type_elements; + + for (i = 0; i < 9; i++) + tm_type_elements[i] = &ffi_type_sint; + + tm_type_elements[9] = &ffi_type_slong; + tm_type_elements[10] = &ffi_type_pointer; + tm_type_elements[11] = NULL; + + /* tm_type can now be used to represent tm argument types and + return types for ffi_prep_cif() */ + @} +@end example + +@node Complex +@subsection Complex Types + +@code{libffi} supports the complex types defined by the C99 +standard (@code{_Complex float}, @code{_Complex double} and +@code{_Complex long double} with the built-in type descriptors +@code{ffi_type_complex_float}, @code{ffi_type_complex_double} and +@code{ffi_type_complex_longdouble}. + +Custom complex types like @code{_Complex int} can also be used. +An @code{ffi_type} object has to be defined to describe the +complex type to @code{libffi}. + +@tindex ffi_type +@deftp {Data type} ffi_type +@table @code +@item size_t size +This must be manually set to the size of the complex type. + +@item unsigned short alignment +This must be manually set to the alignment of the complex type. + +@item unsigned short type +For a complex type, this must be set to @code{FFI_TYPE_COMPLEX}. + +@item ffi_type **elements + +This is a @samp{NULL}-terminated array of pointers to +@code{ffi_type} objects.

However, this is +necessarily platform-specific. + +@c FIXME: document the platforms + +@node The Closure API +@section The Closure API + +@code{libffi} also provides a way to write a generic function -- a +function that can accept and decode any combination of arguments. +This can be useful when writing an interpreter, or to provide wrappers +for arbitrary functions. + +This facility is called the @dfn{closure API}. Closures are not +supported on all platforms; you can check the @code{FFI_CLOSURES} +define to determine whether they are supported on the current +platform. +@cindex closures +@cindex closure API +@findex FFI_CLOSURES + +Because closures work by assembling a tiny function at runtime, they +require special allocation on platforms that have a non-executable +heap. Memory management for closures is handled by a pair of +functions: + +@findex ffi_closure_alloc +@defun void *ffi_closure_alloc (size_t @var{size}, void **@var{code}) +Allocate a chunk of memory holding @var{size} bytes. This returns a +pointer to the writable address, and sets *@var{code} to the +corresponding executable address. + +@var{size} should be sufficient to hold a @code{ffi_closure} object. +@end defun + +@findex ffi_closure_free +@defun void ffi_closure_free (void *@var{writable}) +Free memory allocated using @code{ffi_closure_alloc}. The argument is +the writable address that was returned. +@end defun + +Once you have allocated the memory for a closure, you must construct a +@code{ffi_cif} describing the function call.

However, +integral types narrower than the system register size are widened. In +these cases your program may assume that @var{ret} points to an +@code{ffi_arg} object. + +@item args +A vector of pointers to memory holding the arguments to the function. + +@item user_data +The same @var{user_data} that was passed to +@code{ffi_prep_closure_loc}. +@end table +@end table + +@code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything +went ok, and one of the other @code{ffi_status} values on error. + +After calling @code{ffi_prep_closure_loc}, you can cast @var{codeloc} +to the appropriate pointer-to-function type. +@end defun + +You may see old code referring to @code{ffi_prep_closure}.

All of + the compile-time options default to reasonable values for use on + most platforms. You might later want to step through various + compile-time and dynamic tuning options. + + For convenience, an include file for code using this malloc is at: + ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h + You don't really need this .h file unless you call functions not + defined in your system include files. The .h file contains only the + excerpts from this file needed for using this malloc on ANSI C/C++ + systems, so long as you haven't changed compile-time options about + naming and tuning parameters. If you do, then you can create your + own malloc.h that does include all settings by cutting at the point + indicated below. Note that you may already by default be using a C + library containing a malloc that is based on some version of this + malloc (for example in linux). You might still want to use the one + in this file to customize settings or to avoid overheads associated + with library versions. + +* Vital statistics: + + Supported pointer/size_t representation: 4 or 8 bytes + size_t MUST be an unsigned type of the same width as + pointers. (If you are using an ancient system that declares + size_t as a signed type, or need it to be a different width + than pointers, you can use a previous release of this malloc + (e.g. 2.7.2) supporting these.) + + Alignment: 8 bytes (default) + This suffices for nearly all current machines and C compilers. + However, you can define MALLOC_ALIGNMENT to be wider than this + if necessary (up to 128bytes), at the expense of using more space. + + Minimum overhead per allocated chunk: 4 or 8 bytes (if 4byte sizes) + 8 or 16 bytes (if 8byte sizes) + Each malloced chunk has a hidden word of overhead holding size + and status information, and additional cross-check word + if FOOTERS is defined. + + Minimum allocated size: 4-byte ptrs: 16 bytes (including overhead) + 8-byte ptrs: 32 bytes (including overhead) + + Even a request for zero bytes (i.e., malloc(0)) returns a + pointer to something of the minimum allocatable size. + The maximum overhead wastage (i.e., number of extra bytes + allocated than were requested in malloc) is less than or equal + to the minimum size, except for requests >= mmap_threshold that + are serviced via mmap(), where the worst case wastage is about + 32 bytes plus the remainder from a system page (the minimal + mmap unit); typically 4096 or 8192 bytes. + + Security: static-safe; optionally more or less + The "security" of malloc refers to the ability of malicious + code to accentuate the effects of errors (for example, freeing + space that is not currently malloc'ed or overwriting past the + ends of chunks) in code that calls malloc. This malloc + guarantees not to modify any memory locations below the base of + heap, i.e., static variables, even in the presence of usage + errors. The routines additionally detect most improper frees + and reallocs. All this holds as long as the static bookkeeping + for malloc itself is not corrupted by some other means. This + is only one aspect of security -- these checks do not, and + cannot, detect all possible programming errors. + + If FOOTERS is defined nonzero, then each allocated chunk + carries an additional check word to verify that it was malloced + from its space. These check words are the same within each + execution of a program using malloc, but differ across + executions, so externally crafted fake chunks cannot be + freed. This improves security by rejecting frees/reallocs that + could corrupt heap memory, in addition to the checks preventing + writes to statics that are always on. This may further improve + security at the expense of time and space overhead. (Note that + FOOTERS may also be worth using with MSPACES.) + + By default detected errors cause the program to abort (calling + "abort()"). You can override this to instead proceed past + errors by defining PROCEED_ON_ERROR. In this case, a bad free + has no effect, and a malloc that encounters a bad address + caused by user overwrites will ignore the bad address by + dropping pointers and indices to all known memory. This may + be appropriate for programs that should continue if at all + possible in the face of programming errors, although they may + run out of memory because dropped memory is never reclaimed. + + If you don't like either of these options, you can define + CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything + else. And if if you are sure that your program using malloc has + no errors or vulnerabilities, you can define INSECURE to 1, + which might (or might not) provide a small performance improvement. + + Thread-safety: NOT thread-safe unless USE_LOCKS defined + When USE_LOCKS is defined, each public call to malloc, free, + etc is surrounded with either a pthread mutex or a win32 + spinlock (depending on WIN32). This is not especially fast, and + can be a major bottleneck. It is designed only to provide + minimal protection in concurrent environments, and to provide a + basis for extensions. If you are using malloc in a concurrent + program, consider instead using ptmalloc, which is derived from + a version of this malloc. (See http://www.malloc.de). + + System requirements: Any combination of MORECORE and/or MMAP/MUNMAP + This malloc can use unix sbrk or any emulation (invoked using + the CALL_MORECORE macro) and/or mmap/munmap or any emulation + (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system + memory. On most unix systems, it tends to work best if both + MORECORE and MMAP are enabled. On Win32, it uses emulations + based on VirtualAlloc. It also uses common C library functions + like memset. + + Compliance: I believe it is compliant with the Single Unix Specification + (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably + others as well. + +* Overview of algorithms + + This is not the fastest, most space-conserving, most portable, or + most tunable malloc ever written. However it is among the fastest + while also being among the most space-conserving, portable and + tunable. Consistent balance across these factors results in a good + general-purpose allocator for malloc-intensive programs. + + In most ways, this malloc is a best-fit allocator. Generally, it + chooses the best-fitting existing chunk for a request, with ties + broken in approximately least-recently-used order. (This strategy + normally maintains low fragmentation.) However, for requests less + than 256bytes, it deviates from best-fit when there is not an + exactly fitting available chunk by preferring to use space adjacent + to that used for the previous small request, as well as by breaking + ties in approximately most-recently-used order. (These enhance + locality of series of small allocations.) And for very large requests + (>= 256Kb by default), it relies on system memory mapping + facilities, if supported. (This helps avoid carrying around and + possibly fragmenting memory used only for large chunks.) + + All operations (except malloc_stats and mallinfo) have execution + times that are bounded by a constant factor of the number of bits in + a size_t, not counting any clearing in calloc or copying in realloc, + or actions surrounding MORECORE and MMAP that have times + proportional to the number of non-contiguous regions returned by + system allocation routines, which is often just 1. + + The implementation is not very modular and seriously overuses + macros. Perhaps someday all C compilers will do as good a job + inlining modular code as can now be done by brute-force expansion, + but now, enough of them seem not to. + + Some compilers issue a lot of warnings about code that is + dead/unreachable only on some platforms, and also about intentional + uses of negation on unsigned types. All known cases of each can be + ignored. + + For a longer but out of date high-level description, see + http://gee.cs.oswego.edu/dl/html/malloc.html + +* MSPACES + If MSPACES is defined, then in addition to malloc, free, etc., + this file also defines mspace_malloc, mspace_free, etc. These + are versions of malloc routines that take an "mspace" argument + obtained using create_mspace, to control all internal bookkeeping. + If ONLY_MSPACES is defined, only these versions are compiled. + So if you would like to use this allocator for only some allocations, + and your system malloc for others, you can compile with + ONLY_MSPACES and then do something like... + static mspace mymspace = create_mspace(0,0); // for example + #define mymalloc(bytes) mspace_malloc(mymspace, bytes) + + (Note: If you only need one instance of an mspace, you can instead + use "USE_DL_PREFIX" to relabel the global malloc.) + + You can similarly create thread-local allocators by storing + mspaces as thread-locals. For example: + static __thread mspace tlms = 0; + void* tlmalloc(size_t bytes) { + if (tlms == 0) tlms = create_mspace(0, 0); + return mspace_malloc(tlms, bytes); + } + void tlfree(void* mem) { mspace_free(tlms, mem); } + + Unless FOOTERS is defined, each mspace is completely independent. + You cannot allocate from one and free to another (although + conformance is only weakly checked, so usage errors are not always + caught). If FOOTERS is defined, then each chunk carries around a tag + indicating its originating mspace, and frees are directed to their + originating spaces. + + ------------------------- Compile-time options --------------------------- + +Be careful in setting #define values for numerical constants of type +size_t. On some systems, literal values are not automatically extended +to size_t precision unless they are explicitly casted. + +WIN32 default: defined if _WIN32 defined + Defining WIN32 sets up defaults for MS environment and compilers. + Otherwise defaults are for unix. + +MALLOC_ALIGNMENT default: (size_t)8 + Controls the minimum alignment for malloc'ed chunks. It must be a + power of two and at least 8, even on machines for which smaller + alignments would suffice. It may be defined as larger than this + though. Note however that code and data structures are optimized for + the case of 8-byte alignment. + +MSPACES default: 0 (false) + If true, compile in support for independent allocation spaces. + This is only supported if HAVE_MMAP is true. + +ONLY_MSPACES default: 0 (false) + If true, only compile in mspace versions, not regular versions. + +USE_LOCKS default: 0 (false) + Causes each call to each public routine to be surrounded with + pthread or WIN32 mutex lock/unlock. (If set true, this can be + overridden on a per-mspace basis for mspace versions.) + +FOOTERS default: 0 + If true, provide extra checking and dispatching by placing + information in the footers of allocated chunks. This adds + space and time overhead. + +INSECURE default: 0 + If true, omit checks for usage errors and heap space overwrites. + +USE_DL_PREFIX default: NOT defined + Causes compiler to prefix all public routines with the string 'dl'. + This can be useful when you only want to use this malloc in one part + of a program, using your regular system malloc elsewhere. + +ABORT default: defined as abort() + Defines how to abort on failed checks. On most systems, a failed + check cannot die with an "assert" or even print an informative + message, because the underlying print routines in turn call malloc, + which will fail again. Generally, the best policy is to simply call + abort(). It's not very useful to do more than this because many + errors due to overwriting will show up as address faults (null, odd + addresses etc) rather than malloc-triggered checks, so will also + abort. Also, most compilers know that abort() does not return, so + can better optimize code conditionally calling it. + +PROCEED_ON_ERROR default: defined as 0 (false) + Controls whether detected bad addresses cause them to bypassed + rather than aborting. If set, detected bad arguments to free and + realloc are ignored. And all bookkeeping information is zeroed out + upon a detected overwrite of freed heap space, thus losing the + ability to ever return it from malloc again, but enabling the + application to proceed. If PROCEED_ON_ERROR is defined, the + static variable malloc_corruption_error_count is compiled in + and can be examined to see if errors have occurred. This option + generates slower code than the default abort policy. + +DEBUG default: NOT defined + The DEBUG setting is mainly intended for people trying to modify + this code or diagnose problems when porting to new platforms. + However, it may also be able to better isolate user errors than just + using runtime checks. The assertions in the check routines spell + out in more detail the assumptions and invariants underlying the + algorithms. The checking is fairly extensive, and will slow down + execution noticeably. Calling malloc_stats or mallinfo with DEBUG + set will attempt to check every non-mmapped allocated and free chunk + in the course of computing the summaries. + +ABORT_ON_ASSERT_FAILURE default: defined as 1 (true) + Debugging assertion failures can be nearly impossible if your + version of the assert macro causes malloc to be called, which will + lead to a cascade of further failures, blowing the runtime stack. + ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(), + which will usually make debugging easier. + +MALLOC_FAILURE_ACTION default: sets errno to ENOMEM, or no-op on win32 + The action to take before "return 0" when malloc fails to be able to + return memory because there is none available. + +HAVE_MORECORE default: 1 (true) unless win32 or ONLY_MSPACES + True if this system supports sbrk or an emulation of it. + +MORECORE default: sbrk + The name of the sbrk-style system routine to call to obtain more + memory. See below for guidance on writing custom MORECORE + functions. The type of the argument to sbrk/MORECORE varies across + systems. It cannot be size_t, because it supports negative + arguments, so it is normally the signed type of the same width as + size_t (sometimes declared as "intptr_t"). It doesn't much matter + though. Internally, we only call it with arguments less than half + the max value of a size_t, which should work across all reasonable + possibilities, although sometimes generating compiler warnings. See + near the end of this file for guidelines for creating a custom + version of MORECORE. + +MORECORE_CONTIGUOUS default: 1 (true) + If true, take advantage of fact that consecutive calls to MORECORE + with positive arguments always return contiguous increasing + addresses. This is true of unix sbrk. It does not hurt too much to + set it true anyway, since malloc copes with non-contiguities. + Setting it false when definitely non-contiguous saves time + and possibly wasted space it would take to discover this though. + +MORECORE_CANNOT_TRIM default: NOT defined + True if MORECORE cannot release space back to the system when given + negative arguments. This is generally necessary only if you are + using a hand-crafted MORECORE function that cannot handle negative + arguments. + +HAVE_MMAP default: 1 (true) + True if this system supports mmap or an emulation of it. If so, and + HAVE_MORECORE is not true, MMAP is used for all system + allocation. If set and HAVE_MORECORE is true as well, MMAP is + primarily used to directly allocate very large blocks. It is also + used as a backup strategy in cases where MORECORE fails to provide + space from system. Note: A single call to MUNMAP is assumed to be + able to unmap memory that may have be allocated using multiple calls + to MMAP, so long as they are adjacent. + +HAVE_MREMAP default: 1 on linux, else 0 + If true realloc() uses mremap() to re-allocate large blocks and + extend or shrink allocation spaces. + +MMAP_CLEARS default: 1 on unix + True if mmap clears memory so calloc doesn't need to. This is true + for standard unix mmap using /dev/zero. + +USE_BUILTIN_FFS default: 0 (i.e., not used) + Causes malloc to use the builtin ffs() function to compute indices. + Some compilers may recognize and intrinsify ffs to be faster than the + supplied C version. Also, the case of x86 using gcc is special-cased + to an asm instruction, so is already as fast as it can be, and so + this setting has no effect. (On most x86s, the asm version is only + slightly faster than the C version.) + +malloc_getpagesize default: derive from system includes, or 4096. + The system page size. To the extent possible, this malloc manages + memory from the system in page-size units. This may be (and + usually is) a function rather than a constant. This is ignored + if WIN32, where page size is determined using getSystemInfo during + initialization. + +USE_DEV_RANDOM default: 0 (i.e., not used) + Causes malloc to use /dev/random to initialize secure magic seed for + stamping footers. Otherwise, the current time is used. + +NO_MALLINFO default: 0 + If defined, don't compile "mallinfo". This can be a simple way + of dealing with mismatches between system declarations and + those in this file. + +MALLINFO_FIELD_TYPE default: size_t + The type of the fields in the mallinfo struct. This was originally + defined as "int" in SVID etc, but is more usefully defined as + size_t. The value is used only if HAVE_USR_INCLUDE_MALLOC_H is not set + +REALLOC_ZERO_BYTES_FREES default: not defined + This should be set if a call to realloc with zero bytes should + be the same as a call to free. Some people think it should. Otherwise, + since this malloc returns a unique pointer for malloc(0), so does + realloc(p, 0). + +LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H +LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H, LACKS_ERRNO_H +LACKS_STDLIB_H default: NOT defined unless on WIN32 + Define these if your system does not have these header files. + You might need to manually insert some of the declarations they provide. + +DEFAULT_GRANULARITY default: page size if MORECORE_CONTIGUOUS, + system_info.dwAllocationGranularity in WIN32, + otherwise 64K. + Also settable using mallopt(M_GRANULARITY, x) + The unit for allocating and deallocating memory from the system. On + most systems with contiguous MORECORE, there is no reason to + make this more than a page. However, systems with MMAP tend to + either require or encourage larger granularities. You can increase + this value to prevent system allocation functions to be called so + often, especially if they are slow. The value must be at least one + page and must be a power of two. Setting to 0 causes initialization + to either page size or win32 region size. (Note: In previous + versions of malloc, the equivalent of this option was called + "TOP_PAD") + +DEFAULT_TRIM_THRESHOLD default: 2MB + Also settable using mallopt(M_TRIM_THRESHOLD, x) + The maximum amount of unused top-most memory to keep before + releasing via malloc_trim in free(). Automatic trimming is mainly + useful in long-lived programs using contiguous MORECORE. Because + trimming via sbrk can be slow on some systems, and can sometimes be + wasteful (in cases where programs immediately afterward allocate + more large chunks) the value should be high enough so that your + overall system performance would improve by releasing this much + memory. As a rough guide, you might set to a value close to the + average size of a process (program) running on your system. + Releasing this much memory would allow such a process to run in + memory. Generally, it is worth tuning trim thresholds when a + program undergoes phases where several large chunks are allocated + and released in ways that can reuse each other's storage, perhaps + mixed with phases where there are no such chunks at all. The trim + value must be greater than page size to have any useful effect. To + disable trimming completely, you can set to MAX_SIZE_T. Note that the trick + some people use of mallocing a huge space and then freeing it at + program startup, in an attempt to reserve system memory, doesn't + have the intended effect under automatic trimming, since that memory + will immediately be returned to the system. + +DEFAULT_MMAP_THRESHOLD default: 256K + Also settable using mallopt(M_MMAP_THRESHOLD, x) + The request size threshold for using MMAP to directly service a + request. Requests of at least this size that cannot be allocated + using already-existing space will be serviced via mmap. (If enough + normal freed space already exists it is used instead.) Using mmap + segregates relatively large chunks of memory so that they can be + individually obtained and released from the host system. A request + serviced through mmap is never reused by any other request (at least + not directly; the system may just so happen to remap successive + requests to the same locations). Segregating space in this way has + the benefits that: Mmapped space can always be individually released + back to the system, which helps keep the system level memory demands + of a long-lived program low. Also, mapped memory doesn't become + `locked' between other chunks, as can happen with normally allocated + chunks, which means that even trimming via malloc_trim would not + release them. However, it has the disadvantage that the space + cannot be reclaimed, consolidated, and then used to service later + requests, as happens with normal chunks. The advantages of mmap + nearly always outweigh disadvantages for "large" chunks, but the + value of "large" may vary across systems. The default is an + empirically derived value that works well in most systems. You can + disable mmap by setting to MAX_SIZE_T. + +*/ + +#if defined __linux__ && !defined _GNU_SOURCE +/* mremap() on Linux requires this via sys/mman.h */ +#define _GNU_SOURCE 1 +#endif + +#ifndef WIN32 +#ifdef _WIN32 +#define WIN32 1 +#endif /* _WIN32 */ +#endif /* WIN32 */ +#ifdef WIN32 +#define WIN32_LEAN_AND_MEAN +#include +#define HAVE_MMAP 1 +#define HAVE_MORECORE 0 +#define LACKS_UNISTD_H +#define LACKS_SYS_PARAM_H +#define LACKS_SYS_MMAN_H +#define LACKS_STRING_H +#define LACKS_STRINGS_H +#define LACKS_SYS_TYPES_H +#define LACKS_ERRNO_H +#define MALLOC_FAILURE_ACTION +#define MMAP_CLEARS 0 /* WINCE and some others apparently don't clear */ +#endif /* WIN32 */ + +#ifdef __OS2__ +#define INCL_DOS +#include +#define HAVE_MMAP 1 +#define HAVE_MORECORE 0 +#define LACKS_SYS_MMAN_H +#endif /* __OS2__ */ + +#if defined(DARWIN) || defined(_DARWIN) +/* Mac OSX docs advise not to use sbrk; it seems better to use mmap */ +#ifndef HAVE_MORECORE +#define HAVE_MORECORE 0 +#define HAVE_MMAP 1 +#endif /* HAVE_MORECORE */ +#endif /* DARWIN */ + +#ifndef LACKS_SYS_TYPES_H +#include /* For size_t */ +#endif /* LACKS_SYS_TYPES_H */ + +/* The maximum possible size_t value has all bits set */ +#define MAX_SIZE_T (~(size_t)0) + +#ifndef ONLY_MSPACES +#define ONLY_MSPACES 0 +#endif /* ONLY_MSPACES */ +#ifndef MSPACES +#if ONLY_MSPACES +#define MSPACES 1 +#else /* ONLY_MSPACES */ +#define MSPACES 0 +#endif /* ONLY_MSPACES */ +#endif /* MSPACES */ +#ifndef MALLOC_ALIGNMENT +#define MALLOC_ALIGNMENT ((size_t)8U) +#endif /* MALLOC_ALIGNMENT */ +#ifndef FOOTERS +#define FOOTERS 0 +#endif /* FOOTERS */ +#ifndef ABORT +#define ABORT abort() +#endif /* ABORT */ +#ifndef ABORT_ON_ASSERT_FAILURE +#define ABORT_ON_ASSERT_FAILURE 1 +#endif /* ABORT_ON_ASSERT_FAILURE */ +#ifndef PROCEED_ON_ERROR +#define PROCEED_ON_ERROR 0 +#endif /* PROCEED_ON_ERROR */ +#ifndef USE_LOCKS +#define USE_LOCKS 0 +#endif /* USE_LOCKS */ +#ifndef INSECURE +#define INSECURE 0 +#endif /* INSECURE */ +#ifndef HAVE_MMAP +#define HAVE_MMAP 1 +#endif /* HAVE_MMAP */ +#ifndef MMAP_CLEARS +#define MMAP_CLEARS 1 +#endif /* MMAP_CLEARS */ +#ifndef HAVE_MREMAP +#ifdef linux +#define HAVE_MREMAP 1 +#else /* linux */ +#define HAVE_MREMAP 0 +#endif /* linux */ +#endif /* HAVE_MREMAP */ +#ifndef MALLOC_FAILURE_ACTION +#define MALLOC_FAILURE_ACTION errno = ENOMEM; +#endif /* MALLOC_FAILURE_ACTION */ +#ifndef HAVE_MORECORE +#if ONLY_MSPACES +#define HAVE_MORECORE 0 +#else /* ONLY_MSPACES */ +#define HAVE_MORECORE 1 +#endif /* ONLY_MSPACES */ +#endif /* HAVE_MORECORE */ +#if !HAVE_MORECORE +#define MORECORE_CONTIGUOUS 0 +#else /* !HAVE_MORECORE */ +#ifndef MORECORE +#define MORECORE sbrk +#endif /* MORECORE */ +#ifndef MORECORE_CONTIGUOUS +#define MORECORE_CONTIGUOUS 1 +#endif /* MORECORE_CONTIGUOUS */ +#endif /* HAVE_MORECORE */ +#ifndef DEFAULT_GRANULARITY +#if MORECORE_CONTIGUOUS +#define DEFAULT_GRANULARITY (0) /* 0 means to compute in init_mparams */ +#else /* MORECORE_CONTIGUOUS */ +#define DEFAULT_GRANULARITY ((size_t)64U * (size_t)1024U) +#endif /* MORECORE_CONTIGUOUS */ +#endif /* DEFAULT_GRANULARITY */ +#ifndef DEFAULT_TRIM_THRESHOLD +#ifndef MORECORE_CANNOT_TRIM +#define DEFAULT_TRIM_THRESHOLD ((size_t)2U * (size_t)1024U * (size_t)1024U) +#else /* MORECORE_CANNOT_TRIM */ +#define DEFAULT_TRIM_THRESHOLD MAX_SIZE_T +#endif /* MORECORE_CANNOT_TRIM */ +#endif /* DEFAULT_TRIM_THRESHOLD */ +#ifndef DEFAULT_MMAP_THRESHOLD +#if HAVE_MMAP +#define DEFAULT_MMAP_THRESHOLD ((size_t)256U * (size_t)1024U) +#else /* HAVE_MMAP */ +#define DEFAULT_MMAP_THRESHOLD MAX_SIZE_T +#endif /* HAVE_MMAP */ +#endif /* DEFAULT_MMAP_THRESHOLD */ +#ifndef USE_BUILTIN_FFS +#define USE_BUILTIN_FFS 0 +#endif /* USE_BUILTIN_FFS */ +#ifndef USE_DEV_RANDOM +#define USE_DEV_RANDOM 0 +#endif /* USE_DEV_RANDOM */ +#ifndef NO_MALLINFO +#define NO_MALLINFO 0 +#endif /* NO_MALLINFO */ +#ifndef MALLINFO_FIELD_TYPE +#define MALLINFO_FIELD_TYPE size_t +#endif /* MALLINFO_FIELD_TYPE */ + +/* + mallopt tuning options.

If that bit is *clear*, then the + word before the current chunk size contains the previous chunk + size, and can be used to find the front of the previous chunk. + The very first chunk allocated always has this bit set, preventing + access to non-existent (or non-owned) memory. If pinuse is set for + any given chunk, then you CANNOT determine the size of the + previous chunk, and might even get a memory addressing fault when + trying to do so. + + The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of + the chunk size redundantly records whether the current chunk is + inuse. This redundancy enables usage checks within free and realloc, + and reduces indirection when freeing and consolidating chunks. + + Each freshly allocated chunk must have both cinuse and pinuse set. + That is, each allocated chunk borders either a previously allocated + and still in-use chunk, or the base of its memory arena. This is + ensured by making all allocations from the the `lowest' part of any + found chunk. Further, no free chunk physically borders another one, + so each free chunk is known to be preceded and followed by either + inuse chunks or the ends of memory. + + Note that the `foot' of the current chunk is actually represented + as the prev_foot of the NEXT chunk. This makes it easier to + deal with alignments etc but can be very confusing when trying + to extend or adapt this code. + + The exceptions to all this are + + 1. The special chunk `top' is the top-most available chunk (i.e., + the one bordering the end of available memory). It is treated + specially. Top is never included in any bin, is used only if + no other chunk is available, and is released back to the + system if it is very large (see M_TRIM_THRESHOLD). In effect, + the top chunk is treated as larger (and thus less well + fitting) than any other available chunk. The top chunk + doesn't update its trailing size field since there is no next + contiguous chunk that would have to index off it. However, + space is still allocated for it (TOP_FOOT_SIZE) to enable + separation or merging when space is extended. + + 3.

This is a + streamlined version of the approach described by William Robertson + et al in "Run-time Detection of Heap-based Overflows" LISA'03 + http://www.usenix.org/events/lisa03/tech/robertson.html The footer + of an inuse chunk holds the xor of its mstate and a random seed, + that is checked upon calls to free() and realloc(). This is + (probablistically) unguessable from outside the program, but can be + computed by any code successfully malloc'ing any chunk, so does not + itself provide protection against code that has already broken + security through some other means.
