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

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>.
