+@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.
+

+
+Although @samp{libffi} has no special support for unions or

+
+@tindex ffi_type
+@deftp ffi_type
+The @code{ffi_type} has the following members:

+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}

+The following example initializes a @code{ffi_type} object

+@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.

+
+   The closure API allows interpreted functions to be packaged up

+   function pointer.
+
