Attempt to lock a mutex
#include <pthread.h> int pthread_mutex_trylock( pthread_mutex_t* mutex );
- A pointer to the pthread_mutex_t object that you want to try to lock.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_mutex_trylock() function attempts to lock the mutex mutex, but doesn't block the calling thread if the mutex is already locked.
- Insufficient resources available to lock the mutex.
- The mutex was already locked.
- The mutex is invalid, or it has died (see SyncMutexEvent() ).
