libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The _sleepon_lock() function locks the mutex associated with the sleepon structure, l.
You must call this function before calling _sleepon_wait(), _sleepon_signal(), or _sleepon_broadcast().
The _sleepon_lock() function returns the same values as pthread_mutex_lock().
