Exit | | |<^. R0 |<^. Number of guaranteed slots free | || < 0 indicates over worst case limit, but may still be free slots | h4. Use This call returns the minimum number of slots guaranteed free. The calculation assumes the worst case of data structure overheads that could occur, so it is likely that more slots can in fact be used. If this guaranteed free slot count is exceeded this call will return negative values, and the return status of [[Sound_QSchedule]] must be carefully monitored to observe when overflow occurs.
