+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 part of what is 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.
+
+     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.

+
+2.3.1 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.

+2.6 Closure Example
+===================
+
+A trivial example that creates a new 'puts' by binding 'fputs' with
+'stdin'.
+
+     #include <stdio.h>
+     #include <ffi.h>
+
+     /* Acts like puts with the file given at time of enclosure. */
+     void puts_binding(ffi_cif *cif, void *ret, void* args[],
+                       void *stream)
+     {
+       *(ffi_arg *)ret = fputs(*(char **)args[0], (FILE *)stream);
+     }
+
+     typedef int (*puts_t)(char *);
+
+     int main()
+     {
+       ffi_cif cif;
+       ffi_type *args[1];
+       ffi_closure *closure;
+
+       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,
+                            &ffi_type_sint, args) == FFI_OK)
+             {
+               /* Initialize the closure, setting stream to stdout */
+               if (ffi_prep_closure_loc(closure, &cif, puts_binding,
+                                        stdout, bound_puts) == FFI_OK)
+                 {
+                   rc = ((puts_t)bound_puts)("Hello World!");
+                   /* rc now holds the result of the call to fputs */
+                 }
+             }
+         }
+
+       /* Deallocate both closure, and bound_puts */
+       ffi_closure_free(closure);
+
+       return 0;
+     }

+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.
