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.
