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>.
