Threads::SpinRWLock Class Reference

Is an alternative to ReadWriteLock. It is a lock which causes a thread trying to acquire it to simply wait in a loop ("spin") while repeatedly checking if the lock is available. Because they avoid overhead from operating system process re-scheduling or context switching, spinlocks are efficient if threads are only likely to be blocked for a short period. More...
