#ifndef RAGE_SOUND_NULL
#define RAGE_SOUND_NULL

/* RageSound_Null fakes playing sounds having GetPosition()
 * return seconds since the constructor was called.
 *
 * Only tested in linux, but intended to work across the globe.
 * ( uses time_t, sleep() and nanosleep() from <time.h> )
 *
 * The timing probably isn't accurate, but at least it is fairly
 * steady.  Someone with more knowledge of RageSound, feel free
 * to play around with this (not that it's any sort of priority).
