+Status
+======
+
+libffi-3.1 was released on May 19, 2014.  Check the libffi web page
+for updates: <URL:http://sourceware.org/libffi/>.
+
+
+What is libffi?
+===============
+
+Compilers for high level languages generate code that follow certain
+conventions. 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.
+
+

+above.
+
+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.
+
+If you're building libffi directly from version control, configure won't
+exist yet; run ./autogen.sh first.
+
+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.
+
+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\"
+
+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.
+
+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.)
+
+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".

+Authors & Credits
+=================
+
+libffi was originally written by Anthony Green <green@moxielogic.com>.
+
+The developers of the GNU Compiler Collection project have made
+innumerable valuable contributions.  See the ChangeLog file for
+details.
+
+Some of the ideas behind libffi were inspired by Gianni Mariani's free
+gencall library for Silicon Graphics machines.
+
+The closure mechanism was designed and implemented by Kresten Krab
+Thorup.
+
+Major processor architecture ports were contributed by the following
+developers:
+
+aarch64		Marcus Shawcroft, James Greenhalgh
+alpha		Richard Henderson
+arm		Raffaele Sena
+blackfin        Alexandre Keunecke I. de Mendonca
+cris		Simon Posnjak, Hans-Peter Nilsson

+m88k		Miod Vallat
+microblaze	Nathan Rossi

+moxie		Anthony Green
+nios ii		Sandra Loosemore

+powerpc		Geoffrey Keating, Andreas Tobler, 
+			 David Edelsohn, John Hornkvist
+powerpc64	Jakub Jelinek

+sparc		Anthony Green, Gordon Irlam
+tile-gx/tilepro Walter Lee
+vax		Miod Vallat
+x86		Anthony Green, Jon Beniston
+x86-64		Bo Thorsen
+xtensa		Chris Zankel
+
+Jesper Skov and Andrew Haley both did more than their fair share of
+stepping through the code and tracking down bugs.
+
+Thanks also to Tom Tromey for bug fixes, documentation and
+configuration help.
+
+Thanks to Jim Blandy, who provided some useful feedback on the libffi
+interface.
+
+Andreas Tobler has done a tremendous amount of work on the testsuite.
+
+Alex Oliva solved the executable page problem for SElinux.
+
+The list above is almost certainly incomplete and inaccurate.  I'm
+happy to make corrections or additions upon request.
+
+If you have a problem, or have found a bug, please send a note to the
+author at green@moxielogic.com, or the project mailing list at
+libffi-discuss@sourceware.org.

+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.

+1 What is libffi?
+*****************
+
+Compilers for high level languages generate code that follow certain
+conventions.  These conventions are necessary, in part, for separate
+compilation to work.  One such convention is the "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 "ABI" or
+"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.  '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.

+File: libffi.info,  Node: The Basics,  Next: Simple Example,  Up: Using libffi
+
+2.1 The Basics
+==============
+
+'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 '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
+'ffi_cif'.  The "cif" in 'ffi_cif' stands for Call InterFace.  To
+prepare a call interface object, use the function 'ffi_prep_cif'.
+
+ -- Function: ffi_status ffi_prep_cif (ffi_cif *CIF, ffi_abi ABI,
+          unsigned int NARGS, ffi_type *RTYPE, ffi_type **ARGTYPES)
+     This initializes CIF according to the given parameters.
+
+     ABI is the ABI to use; normally 'FFI_DEFAULT_ABI' is what you want.
+     *note Multiple ABIs:: for more information.
+
+     NARGS is the number of arguments that this function accepts.
+
+     RTYPE is a pointer to an 'ffi_type' structure that describes the
+     return type of the function.  *Note Types::.
+
+     ARGTYPES is a vector of 'ffi_type' pointers.  ARGTYPES must have
+     NARGS elements.  If NARGS is 0, this argument is ignored.
+
+     'ffi_prep_cif' returns a 'libffi' status code, of type
+     'ffi_status'.  This will be either 'FFI_OK' if everything worked
+     properly; 'FFI_BAD_TYPEDEF' if one of the 'ffi_type' objects is
+     incorrect; or 'FFI_BAD_ABI' if the ABI parameter is invalid.
+
+   If the function being called is variadic (varargs) then
+'ffi_prep_cif_var' must be used instead of 'ffi_prep_cif'.
+
+ -- Function: ffi_status ffi_prep_cif_var (ffi_cif *CIF, ffi_abi varabi,
+          unsigned int NFIXEDARGS, unsigned int varntotalargs, ffi_type
+          *RTYPE, ffi_type **ARGTYPES)
+     This initializes CIF according to the given parameters for a call
+     to a variadic function.  In general it's operation is the same as
+     for 'ffi_prep_cif' except that:
+
+     NFIXEDARGS is the number of fixed arguments, prior to any variadic
+     arguments.  It must be greater than zero.
+
+     NTOTALARGS the total number of arguments, including variadic and
+     fixed arguments.
+
+     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 'ffi_prep_cif_var' with
+     NFIXEDARGS=NOTOTALARGS is NOT equivalent to a call to
+     'ffi_prep_cif'.
+
+   To call a function using an initialized 'ffi_cif', use the 'ffi_call'
+function:
+
+ -- Function: void ffi_call (ffi_cif *CIF, void *FN, void *RVALUE, void
+          **AVALUES)
+     This calls the function FN according to the description given in
+     CIF.  CIF must have already been prepared using 'ffi_prep_cif'.
+
+     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 CIF declares that the function
+     returns 'void' (using 'ffi_type_void'), then RVALUE is ignored.
+
+     AVALUES is a vector of 'void *' pointers that point to the memory
+     locations holding the argument values for a call.  If CIF declares
+     that the function has no arguments (i.e., NARGS was 0), then
+     AVALUES is ignored.  Note that argument values may be modified by
+     the callee (for instance, structs passed by value); the burden of
+     copying pass-by-value arguments is placed on the caller.
+

+
+2.2 Simple Example
+==================
+
+Here is a trivial example that calls 'puts' a few times.
+
+     #include <stdio.h>
+     #include <ffi.h>
+
+     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, 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, puts, &rc, values);
+         }
+
+       return 0;
+     }

+
+
+File: libffi.info,  Node: Primitive Types,  Next: Structures,  Up: Types
+
+2.3.1 Primitive Types
+---------------------
+
+'Libffi' provides a number of built-in type descriptors that can be used
+to describe argument and return types:
+
+'ffi_type_void'
+     The type 'void'.  This cannot be used for argument types, only for
+     return values.
+
+'ffi_type_uint8'
+     An unsigned, 8-bit integer type.
+
+'ffi_type_sint8'
+     A signed, 8-bit integer type.
+
+'ffi_type_uint16'
+     An unsigned, 16-bit integer type.
+
+'ffi_type_sint16'
+     A signed, 16-bit integer type.
+
+'ffi_type_uint32'
+     An unsigned, 32-bit integer type.
+
+'ffi_type_sint32'
+     A signed, 32-bit integer type.
+
+'ffi_type_uint64'
+     An unsigned, 64-bit integer type.
+
+'ffi_type_sint64'
+     A signed, 64-bit integer type.
+
+'ffi_type_float'
+     The C 'float' type.
+
+'ffi_type_double'
+     The C 'double' type.
+
+'ffi_type_uchar'
+     The C 'unsigned char' type.
+
+'ffi_type_schar'
+     The C 'signed char' type.  (Note that there is not an exact
+     equivalent to the C 'char' type in 'libffi'; ordinarily you should
+     either use 'ffi_type_schar' or 'ffi_type_uchar' depending on
+     whether 'char' is signed.)
+
+'ffi_type_ushort'
+     The C 'unsigned short' type.
+
+'ffi_type_sshort'
+     The C 'short' type.
+
+'ffi_type_uint'
+     The C 'unsigned int' type.
+
+'ffi_type_sint'
+     The C 'int' type.
+
+'ffi_type_ulong'
+     The C 'unsigned long' type.
+
+'ffi_type_slong'
+     The C 'long' type.
+
+'ffi_type_longdouble'
+     On platforms that have a C 'long double' type, this is defined.  On
+     other platforms, it is not.
+
+'ffi_type_pointer'
+     A generic 'void *' pointer.  You should use this for all pointers,
+     regardless of their real type.
+
+   Each of these is of type 'ffi_type', so you must take the address
+when passing to 'ffi_prep_cif'.
+
+
+File: libffi.info,  Node: Structures,  Next: Type Example,  Prev: Primitive Types,  Up: Types
+
+2.3.2 Structures
+----------------
+
+Although 'libffi' has no special support for unions or bit-fields, it is
+perfectly happy passing structures back and forth.  You must first
+describe the structure to 'libffi' by creating a new 'ffi_type' object
+for it.
+
+ -- Data type: ffi_type
+     The 'ffi_type' has the following members:
+     'size_t size'
+          This is set by 'libffi'; you should initialize it to zero.
+
+     'unsigned short alignment'
+          This is set by 'libffi'; you should initialize it to zero.
+
+     'unsigned short type'
+          For a structure, this should be set to 'FFI_TYPE_STRUCT'.
+
+     'ffi_type **elements'
+          This is a 'NULL'-terminated array of pointers to 'ffi_type'
+          objects.  There is one element per field of the struct.
+
+
+File: libffi.info,  Node: Type Example,  Prev: Structures,  Up: Types
+
+2.3.3 Type Example
+------------------
+
+The following example initializes a 'ffi_type' object representing the
+'tm' struct from Linux's 'time.h'.
+
+   Here is how the struct is defined:
+
+     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__;
+     };
+
+   Here is the corresponding code to describe this struct to 'libffi':
+
+         {
+           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() */
+         }
+
+
+File: libffi.info,  Node: Multiple ABIs,  Next: The Closure API,  Prev: Types,  Up: Using libffi
+
+2.4 Multiple ABIs
+=================
+
+A given platform may provide multiple different ABIs at once.  For
+instance, the x86 platform has both 'stdcall' and 'fastcall' functions.
+
+   'libffi' provides some support for this.  However, this is
+necessarily platform-specific.
+
+
+File: libffi.info,  Node: The Closure API,  Next: Closure Example,  Prev: Multiple ABIs,  Up: Using libffi
+
+2.5 The Closure API
+===================
+
+'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 "closure API". Closures are not supported
+on all platforms; you can check the 'FFI_CLOSURES' define to determine
+whether they are supported on the current platform.
+
+   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:
+
+ -- Function: void *ffi_closure_alloc (size_t SIZE, void **CODE)
+     Allocate a chunk of memory holding SIZE bytes.  This returns a
+     pointer to the writable address, and sets *CODE to the
+     corresponding executable address.
+
+     SIZE should be sufficient to hold a 'ffi_closure' object.
+
+ -- Function: void ffi_closure_free (void *WRITABLE)
+     Free memory allocated using 'ffi_closure_alloc'.  The argument is
+     the writable address that was returned.
+
+   Once you have allocated the memory for a closure, you must construct
+a 'ffi_cif' describing the function call.  Finally you can prepare the
+closure function:
+
+ -- Function: ffi_status ffi_prep_closure_loc (ffi_closure *CLOSURE,
+          ffi_cif *CIF, void (*FUN) (ffi_cif *CIF, void *RET, void
+          **ARGS, void *USER_DATA), void *USER_DATA, void *CODELOC)
+     Prepare a closure function.
+
+     CLOSURE is the address of a 'ffi_closure' object; this is the
+     writable address returned by 'ffi_closure_alloc'.
+
+     CIF is the 'ffi_cif' describing the function parameters.
+
+     USER_DATA is an arbitrary datum that is passed, uninterpreted, to
+     your closure function.
+
+     CODELOC is the executable address returned by 'ffi_closure_alloc'.
+
+     FUN is the function which will be called when the closure is
+     invoked.  It is called with the arguments:
+     CIF
+          The 'ffi_cif' passed to 'ffi_prep_closure_loc'.
+
+     RET
+          A pointer to the memory used for the function's return value.
+          FUN must fill this, unless the function is declared as
+          returning 'void'.
+
+     ARGS
+          A vector of pointers to memory holding the arguments to the
+          function.
+
+     USER_DATA
+          The same USER_DATA that was passed to 'ffi_prep_closure_loc'.
+
+     'ffi_prep_closure_loc' will return 'FFI_OK' if everything went ok,
+     and something else on error.
+
+     After calling 'ffi_prep_closure_loc', you can cast CODELOC to the
+     appropriate pointer-to-function type.
+
+   You may see old code referring to 'ffi_prep_closure'.  This function
+is deprecated, as it cannot handle the need for separate writable and
+executable addresses.

+3 Missing Features
+******************
+
+'libffi' is missing a few features.  We welcome patches to add support
+for these.
+
+   * Variadic closures.
+
+   * There is no support for bit fields in structures.
+
+   * The closure API is
+
+   * The "raw" API is undocumented.
+
+   Note that variadic support is very new and tested on a relatively
+small number of platforms.

+@chapter What is libffi?
+
+Compilers for high level languages generate code that follow certain
+conventions.  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.  @samp{Libffi} can be used in such programs to
+provide a bridge from the interpreter program to compiled code.
+
+The @samp{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 @samp{libffi} library really only provides the lowest, machine
+dependent layer of a fully featured foreign function interface.  A
+layer must exist above @samp{libffi} that handles type conversions for
+values passed between the two languages.

+@node The Basics
+@section The Basics
+
+@samp{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 it's 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.
+
+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
+
+
+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.
+
+@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 argument values may be
+modified by the callee (for instance, structs passed by value); the
+burden of copying pass-by-value arguments is placed on the caller.
+@end defun
+
+
+@node Simple Example
+@section Simple Example
+
+Here is a trivial example that calls @code{puts} a few times.
+
+@example
+#include <stdio.h>
+#include <ffi.h>
+
+int main()
+@{
+  ffi_cif cif;

+		       &ffi_type_sint, args) == FFI_OK)
+    @{
+      s = "Hello World!";
+      ffi_call(&cif, puts, &rc, values);
+      /* rc now holds the result of the call to puts */

+      /* values holds a pointer to the function's arg, so to

+
+@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}.  This cannot be used for argument types, only
+for return values.
+
+@item ffi_type_uint8
+@tindex ffi_type_uint8
+An unsigned, 8-bit integer type.
+
+@item ffi_type_sint8
+@tindex ffi_type_sint8
+A signed, 8-bit integer type.
+
+@item ffi_type_uint16
+@tindex ffi_type_uint16
+An unsigned, 16-bit integer type.
+
+@item ffi_type_sint16
+@tindex ffi_type_sint16
+A signed, 16-bit integer type.
+
+@item ffi_type_uint32
+@tindex ffi_type_uint32
+An unsigned, 32-bit integer type.
+
+@item ffi_type_sint32
+@tindex ffi_type_sint32
+A signed, 32-bit integer type.
+
+@item ffi_type_uint64
+@tindex ffi_type_uint64
+An unsigned, 64-bit integer type.
+
+@item ffi_type_sint64
+@tindex ffi_type_sint64
+A signed, 64-bit integer type.
+
+@item ffi_type_float
+@tindex ffi_type_float
+The C @code{float} type.
+
+@item ffi_type_double
+@tindex ffi_type_double
+The C @code{double} type.
+
+@item ffi_type_uchar
+@tindex ffi_type_uchar
+The C @code{unsigned char} type.
+
+@item ffi_type_schar
+@tindex ffi_type_schar
+The C @code{signed char} type.  (Note that there is not an exact
+equivalent to the C @code{char} type in @code{libffi}; ordinarily you
+should either use @code{ffi_type_schar} or @code{ffi_type_uchar}
+depending on whether @code{char} is signed.)
+
+@item ffi_type_ushort
+@tindex ffi_type_ushort
+The C @code{unsigned short} type.
+
+@item ffi_type_sshort
+@tindex ffi_type_sshort
+The C @code{short} type.
+
+@item ffi_type_uint
+@tindex ffi_type_uint
+The C @code{unsigned int} type.
+
+@item ffi_type_sint
+@tindex ffi_type_sint
+The C @code{int} type.
+
+@item ffi_type_ulong
+@tindex ffi_type_ulong
+The C @code{unsigned long} type.
+
+@item ffi_type_slong
+@tindex ffi_type_slong
+The C @code{long} type.
+
+@item ffi_type_longdouble
+@tindex ffi_type_longdouble
+On platforms that have a C @code{long double} type, this is defined.
+On other platforms, it is not.
+
+@item ffi_type_pointer
+@tindex ffi_type_pointer
+A generic @code{void *} pointer.  You should use this for all
+pointers, regardless of their real type.
+@end table
+
+Each of these is of type @code{ffi_type}, so you must take the address
+when passing to @code{ffi_prep_cif}.
+
+
+@node Structures
+@subsection Structures
+
+Although @samp{libffi} has no special support for unions or
+bit-fields, it is perfectly happy passing structures back and forth.
+You must first describe the structure to @samp{libffi} by creating a
+new @code{ffi_type} object for it.
+
+@tindex ffi_type
+@deftp {Data type} ffi_type
+The @code{ffi_type} has the following members:
+@table @code
+@item size_t size
+This is set by @code{libffi}; you should initialize it to zero.
+
+@item unsigned short alignment
+This is set by @code{libffi}; you should initialize it to zero.
+
+@item unsigned short type
+For a structure, this should be set to @code{FFI_TYPE_STRUCT}.
+
+@item ffi_type **elements
+This is a @samp{NULL}-terminated array of pointers to @code{ffi_type}
+objects.  There is one element per field of the struct.
+@end table
+@end deftp
+
+
+@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;

+@code{libffi} provides some support for this.  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.  Finally you can prepare
+the closure function:
+
+@findex ffi_prep_closure_loc
+@defun ffi_status ffi_prep_closure_loc (ffi_closure *@var{closure}, ffi_cif *@var{cif}, void (*@var{fun}) (ffi_cif *@var{cif}, void *@var{ret}, void **@var{args}, void *@var{user_data}), void *@var{user_data}, void *@var{codeloc})
+Prepare a closure function.
+
+@var{closure} is the address of a @code{ffi_closure} object; this is
+the writable address returned by @code{ffi_closure_alloc}.
+
+@var{cif} is the @code{ffi_cif} describing the function parameters.
+
+@var{user_data} is an arbitrary datum that is passed, uninterpreted,
+to your closure function.
+
+@var{codeloc} is the executable address returned by
+@code{ffi_closure_alloc}.
+
+@var{fun} is the function which will be called when the closure is
+invoked.  It is called with the arguments:
+@table @var
+@item cif
+The @code{ffi_cif} passed to @code{ffi_prep_closure_loc}.
+
+@item ret
+A pointer to the memory used for the function's return value.
+@var{fun} must fill this, unless the function is declared as returning
+@code{void}.
+@c FIXME: is this NULL for void-returning functions?
+
+@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
+
+@code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything
+went ok, and something else on error.
+@c FIXME: what?
+
+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}.  This
+function is deprecated, as it cannot handle the need for separate
+writable and executable addresses.
+
+@node Closure Example
+@section Closure Example
+
+A trivial example that creates a new @code{puts} by binding 
+@code{fputs} with @code{stdout}.

+
+  void *bound_puts;
+  int rc;
+
+  /* Allocate closure and bound_puts */
+  closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts);
+
+  if (closure)
+    @{
+      /* Initialize the argument info vectors */
+      args[0] = &ffi_type_pointer;
+
+      /* Initialize the cif */
+      if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1,

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00174.html

+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILE_FLAG, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+#   AX_CONFIGURE_ARGS
+#
+# DESCRIPTION
+#
+#   Helper macro for AX_ENABLE_BUILDDIR.
+#
+#   The traditional way of starting a subdir-configure is running the script
+#   with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
+#   to rely on eval'ing $ac_configure_args however some old autoconf
+#   versions do not provide that. To ensure maximum portability of autoconf
+#   extension macros this helper can be AC_REQUIRE'd so that
+#   $ac_configure_args will alsways be present.
+#
+#   Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
+#   spoiled now and must be replaced by "eval + exit $?".
+#
+#   Example:
+#
+#     AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
+#       AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
+#       eval $SHELL $ac_configure_args || exit $?

+# SYNOPSIS
+#
+#   AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
+#
+# DESCRIPTION
+#
+#   If the current configure was run within the srcdir then we move all
+#   configure-files into a subdir and let the configure steps continue
+#   there. We provide an option --disable-builddir to suppress the move into
+#   a separate builddir.
+#
+#   Defaults:
+#
+#     $1 = $host (overridden with $HOST)
+#     $2 = Makefile.mk
+#     $3 = -all
+#
+#   This macro must be called before AM_INIT_AUTOMAKE. It creates a default
+#   toplevel srcdir Makefile from the information found in the created
+#   toplevel builddir Makefile. It just copies the variables and
+#   rule-targets, each extended with a default rule-execution that recurses
+#   into the build directory of the current "HOST". You can override the
+#   auto-dection through `config.guess` and build-time of course, as in
+#
+#     make HOST=i386-mingw-cross
+#
+#   which can of course set at configure time as well using
+#
+#     configure --host=i386-mingw-cross
+#
+#   After the default has been created, additional rules can be appended
+#   that will not just recurse into the subdirectories and only ever exist
+#   in the srcdir toplevel makefile - these parts are read from the $2 =
+#   Makefile.mk file
+#
+#   The automatic rules are usually scanning the toplevel Makefile for lines
+#   like '#### $host |$builddir' to recognize the place where to recurse
+#   into. Usually, the last one is the only one used. However, almost all
+#   targets have an additional "*-all" rule which makes the script to
+#   recurse into _all_ variants of the current HOST (!!) setting. The "-all"
+#   suffix can be overriden for the macro as well.
+#
+#   a special rule is only given for things like "dist" that will copy the
+#   tarball from the builddir to the sourcedir (or $(PUB)) for reason of
+#   convenience.

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+.Sh DESCRIPTION
+The
+.Nm ffi_call
+function provides a simple mechanism for invoking a function without
+requiring knowledge of the function's interface at compile time.
+.Fa fn
+is called with the values retrieved from the pointers in the
+.Fa avalue
+array. The return value from
+.Fa fn
+is placed in storage pointed to by
+.Fa rvalue .
+.Fa cif
+contains information describing the data types, sizes and alignments of the
+arguments to and return value from
+.Fa fn ,
+and must be initialized with
+.Nm ffi_prep_cif
+before it is used with
+.Nm ffi_call .
+.Pp
+.Fa rvalue
+must point to storage that is sizeof(ffi_arg) or larger for non-floating point
+types. For smaller-sized return value types, the
+.Nm ffi_arg
+or
+.Nm ffi_sarg
+integral type must be used to hold
+the return value.

+   Create a stack frame, setup an argument context, call the callee

+
+   The maximum required argument stack size is provided,
+   ffi_call_SYSV() allocates that stack space then calls the
+   prepare_fn to populate register context and stack.  The
+   argument passing registers are loaded from the register
+   context and the callee called, on return the register passing
+   register are saved back to the context.  Our caller will
+   extract the return value from the final state of the saved
+   register context.
