TutMutexUnlock

TutMutexUnlock — unlock a mutex object

T_BOOL TutMutexUnlock(mutex) 
T_MUTEX mutex;

mutex — mutex object to unlock

TRUE if mutex object was successfully unlocked, FALSE otherwise.

If TutMutexUnlock fails, it returns FALSE and sets the global SmartSockets error number to one of:

T_ERR_OS — an operating system error has occurred. Call the function TutErrNumGetOs to obtain the related OS error value.

T_ERR_TYPE_MISMATCH — the platform does not support threads.

T_ERR_VAL_INVALID — mutex was not a valid mutex object.

TutMutexUnlock unlocks a locked mutex object. Only the thread that owns the lock on mutex can successfully unlock it.

Every call to TutMutexUnlock must balance a previous call to TutMutexLock.

This example attempts to unlock a mutex object:

T_MUTEX mutex; 
... 
if (!TutMutexUnlock(mutex)) { 
  /* error */ 
}
