#define TF_UNUSED

)

(void) x

Stops compiler from producing unused argument or variable warnings.

This is useful mainly in C, because in C++ you can just leave the variable unnamed. However, there are situations where this can be useful even in C++, such as

void
MyClass::Method( int foo )
{
#if defined(__APPLE__)
    TF_UNUSED( foo );
    // do something that doesn't need foo...
#else
    // do something that needs foo
#endif
}
