SYNOPSIS
#include <ffi.h> ffi_status ffi_prep_cif(
ffi_cif *cif,
ffi_abi abi,
unsigned int nargs,
ffi_type *rtype,
ffi_type **atypes);
void ffi_prep_cif_var(
ffi_cif *cif,
ffi_abi abi,
unsigned int nfixedargs,
unsigned int ntotalargs,
ffi_type *rtype,
ffi_type **atypes);
void ffi_call(
ffi_cif *cif,
void (*fn)(void),
void *rvalue,
void **avalue);
DESCRIPTION
The foreign function interface provides a mechanism by which a function
can generate a call to another function at runtime without requiring
knowledge of the called function's interface at compile time.
