NAME
     FFI -- Foreign Function Interface

LIBRARY
     libffi, -lffi

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);

     ffi_status
     ffi_prep_closure(ffi_closure *closure, ffi_cif *cif, void (*fun)(ffi_cif*,void*,void**,void*), void *user_data);

     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.
