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  describes 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>.
