NAME
     ffi_prep_cif -- Prepare a ffi_cif structure for use with ffi_call

SYNOPSIS
     #include <ffi.h>

     ffi_status
     ffi_prep_cif(ffi_cif *cif, ffi_abi abi, unsigned int nargs,
	 ffi_type *rtype, ffi_type **atypes);

DESCRIPTION
     The  ffi_prep_cif	function  prepares  a  ffi_cif	structure  for	use with
     ffi_call abi specifies a set of calling conventions to use.  atypes  is  an
     array  of	nargs  pointers to ffi_type structs that describe the data type,
     size and alignment of each argument.  rtype points to an ffi_type that  de-
     scribes the data type, size and alignment of the return value. Note that to
     call a variadic function ffi_prep_cif_var must be used instead.

RETURN VALUES
     Upon  successful  completion,  ffi_prep_cif returns FFI_OK.  It will return
     FFI_BAD_TYPEDEF if cif is NULL or atypes or rtype is malformed. If abi does
     not refer to a valid ABI, FFI_BAD_ABI will be returned. Available ABIs  are
     defined in <ffitarget.h>.
