- * @brief ACE_Condition variable wrapper, which allows threads to block
- * until shared data changes state.
- *
- * A condition variable enables threads to atomically block and
- * test the condition under the protection of a mutual exclu-
- * sion lock (mutex) until the condition is satisfied. That is,
- * the mutex must have been held by the thread before calling
- * wait or signal on the condition. If the condition is false,
- * a thread blocks on a condition variable and atomically
- * releases the mutex that is waiting for the condition to
- * change. If another thread changes the condition, it may wake
- * up waiting threads by signaling the associated condition
- * variable. The waiting threads, upon awakening, reacquire the
- * mutex and re-evaluate the condition.
- * Note, you can only parameterize <ACE_Condition> with
- * @a ACE_Thread_Mutex, @a ACE_Recursive_Thread_Mutex, or @a ACE_Null_Mutex.
