Description

FFI(3)                   BSD Library Functions Manual                   FFI(3)

NAME
     FFI -- Foreign Function Interface

LIBRARY
     libffi, -lffi

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.
