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.
