83 | This is your typical mutex with signalling implemented via pthreads. | ||
84 | Lock() will return true if and only if the guard is locked on that call. | ||
85 | A thread that already has the guard will receive 'false' if it locks it | ||
86 | again. Use of the stack-based CAGuard::Locker class is highly recommended | ||
87 | to properly manage the recursive nesting. The Wait calls with timeouts | ||
88 | will return true if and only if the timeout period expired. They will | ||
89 | return false if they receive notification any other way. | ||
