摘要： Hybrid lock and unlock capabilities are provided for a threaded computing environment. For example, kernel locking services are selectively employed in conjunction with functions in the POSIX threads standard to provide a lock capability and an unlock capability. The hybrid approach determines which lock scheme to employ by evaluating whether one thread or multiple threads concurrently desire a resource lock. When only one thread desires the lock, the thread is directly assigned resource ownership employing one of an operating system primitive lock process or a hardware lock process. An alternate lock process is used to obtain resource ownership when multiple threads concurrently desire the lock. This alternate process employs at least one function in the POSIX threads standard to implement a queue of waiting threads. A similar hybrid approach to the unlock capability is also provided.
