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. +@cindex FFI +@cindex Foreign Function Interface + + +@node Using libffi +@chapter Using libffi + +@menu +* The Basics:: The basic libffi API. +* Simple Example:: A simple example. +* Types:: libffi type descriptions. +* Multiple ABIs:: Different passing styles on one platform. +* The Closure API:: Writing a generic function. +* Closure Example:: A closure example. +@end menu + + +@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. 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 *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; +@} +@end example + + +@node Types +@section Types + +@menu +* Primitive Types:: Built-in types. +* Structures:: Structure types. +* Type Example:: Structure type example. +@end menu + +@node Primitive Types +@subsection Primitive Types + +@code{Libffi} provides a number of built-in type descriptors that can +be used to describe argument and return types: + +@table @code +@item ffi_type_void +@tindex ffi_type_void +The type @code{void}.
