I have a boost::mutex that’s being used in two threads. The first thread is constantly locking and unlocking the mutex. The second thread only uses the mutex on a certain condition. When this condition occurs, both threads block on the lock. What could possibly causing this?
Some random facts about my program: The mutex is a data member of class shared between the two threads. In the second thread, I am passing a pointer to the mutex to the function that uses it, but in the first thread I’m using the mutex by reference.
Did you remember to unlock the mutex in the main thread after you signal the condition? Alternately, did you get into a deadlock situation?
