ffi_prep_cif(3) BSD Library Functions Manual ffi_prep_cif(3)
NAME
ffi_prep_cif -- Prepare a ffi_cif structure for use with ffi_call or
ffi_prep_closure.
SYNOPSIS
#include <ffi/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 or ffi_prep_closure. 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.
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 <ffi/ppc-ffitarget.h> and <ffi/x86-ffitarget.h>.
