+Status
+======
+
+libffi-3.0.10 was released on XXXXXXXXXX, 2010. 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.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms.
+For specific configuration details and testing status, please

+
+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.
+
+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 --enable-shared --enable-static \
+	CC=path/to/msvcc.sh LD=link \
+	CPP=\"cl -nologo -EP\"
+
+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 prep.ai.mit.edu:/pub/gnu.
+
+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".

+This directory contains the libffi package, which is not part of GCC but
+shipped with GCC as convenience.
+
+Status
+======
+
+libffi-3.0.9 was released on December 31, 2009. 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.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms.
+For specific configuration details and testing status, please
+refer to the wiki page here:

+
+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.
+
+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 --enable-shared --enable-static \
+	CC=path/to/msvcc.sh LD=link \
+	CPP=\"cl -nologo -EP\"
+
+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 prep.ai.mit.edu:/pub/gnu.
+
+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".

+
+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.

+
+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.
+     `libffi' does not yet handle varargs functions; see *note Missing
+     Features:: for more information.
+
+     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.
+
+   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 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.
+     If RVALUE is `NULL', then the return value is discarded.
+
+     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.

+
+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;
+       int 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_uint, 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.
+
+ -- 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.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,  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.
+
+   * There is no support for calling varargs functions.  This may work
+     on some platforms, depending on how the ABI is defined, but it is
+     not reliable.
+
+   * There is no support for bit fields in structures.
+
+   * The closure API is
+
+   * The "raw" API is undocumented.

+@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.
+@samp{libffi} does not yet handle varargs functions; see @ref{Missing
+Features} for more information.
+
+@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
+
+
+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 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.  If @var{rvalue} is @samp{NULL}, then the return value is
+discarded.
+
+@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.
+@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 *args[1];
+  void *values[1];
+  char *s;
+  int 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_uint, 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!";

+@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}.  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 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.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 Multiple ABIs
+@section Multiple ABIs
+
+A given platform may provide multiple different ABIs at once.  For
+instance, the x86 platform has both @samp{stdcall} and @samp{fastcall}
+functions.
+
+@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.

+
+	* ffi.c (ffi_prep_cif_machdep): Fixed arg flags. Second arg
+	is only processed if the first is either a float or double.
+
+Mon Oct  7 15:33:59 1996  Anthony Green  <green@rtl.cygnus.com>

+
+Tue Oct  1 17:11:02 1996  Anthony Green  <green@rtl.cygnus.com>
+
+	* ffi.c, o32.S, object.mak: Created

+
+Mon Oct 14 13:31:24 1996  Anthony Green  <green@rtl.cygnus.com>
+
+	* v8.S (ffi_call_V8): Gordon rewrites this again. It looks
+	great now.
+
+	* ffi.c (ffi_call): The comment about hijacked registers
+	is no longer valid after gordoni hacked v8.S.
+
+        * v8.S (ffi_call_V8): Rewrote with gordoni. Much simpler.
+	
+	* v8.S, ffi.c: ffi_call() had changed to accept more than

+Status
+======
+
+libffi-3.0.10 was released on XXXXXXXXXX, 2010. 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.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms.
+For specific configuration details and testing status, please

+
+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.
+
+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 LD=link CPP=\"cl -nologo -EP\"
+
+For 64-bit Windows builds, use CC="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.)
+
+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 prep.ai.mit.edu:/pub/gnu.
+
+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@redhat.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:
+
+alpha		Richard Henderson
+arm		Raffaele Sena
+cris		Simon Posnjak, Hans-Peter Nilsson
+frv		Anthony Green
+ia64		Hans Boehm
+m32r		Kazuhiro Inaoka
+m68k		Andreas Schwab
+mips		Anthony Green, Casey Marshall
+mips64		David Daney
+pa		Randolph Chung, Dave Anglin, Andreas Tobler
+powerpc		Geoffrey Keating, Andreas Tobler, 
+			 David Edelsohn, John Hornkvist
+powerpc64	Jakub Jelinek
+s390		Gerhard Tonn, Ulrich Weigand
+sh		Kaz Kojima
+sh64		Kaz Kojima
+sparc		Anthony Green, Gordon Irlam
+x86		Anthony Green, Jon Beniston
+x86-64		Bo Thorsen
+
+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
+green@redhat.com.

+   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
