SYNOPSIS
     #include <ffi/ffi.h>

     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);
