If I use mutex blocking like this
will the mutex be unblocked if the thread terminates inside the Send function?Code:pthread_mutex_lock (&send_mutex); try { Send( pBuffer, ulMsgSize ); } catch(...) { pthread_mutex_unlock (&send_mutex); throw; } pthread_mutex_unlock (&send_mutex);
I know with semaphores you can use the SEM_UNDO flag for that purpose, but how can you do it with mutexes?
Based on what is says here, I'm going to guess the lock isn't released until you explicitly do so.
Why not write a small program and test your theories.An equal number of pthread_mutex_unlock operations must be performed before the mutex returns to the unlocked state.
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
what's that? never heard of itmutex blocking
