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
