stk::test::rwmutex Namespace Reference

Namespace of RWMutex test. More...

Classes
class	ConcurrentReadersTask
	Tests that multiple readers can acquire ReadLock() simultaneously. More...
class	WriterExclusivityTask
	Tests that writer Lock()/Unlock() provides mutual exclusion. More...
class	WriterStarvationTask
	Tests writer preference policy: writers don't starve under reader flood. More...
class	TimedReadLockTask
	Tests TimedReadLock() timeout behavior. More...
class	TimedWriteLockTask
	Tests TimedLock() timeout behavior for writers. More...
class	TryReadLockWhileWriterTask
	Tests TryReadLock() returns false when writer is active; true after release. More...
class	ReadUnlockWakesWriterTask
	Tests that the last reader releasing wakes a waiting writer immediately. More...
class	WriterPriorityTask
	Tests writer preference policy: new readers are blocked when writers are waiting. More...
class	ReaderWriterAlternationTask
	Tests alternating read and write phases with multiple concurrent readers. More...
class	StressTestTask
	Stress test mixing readers and writers under full five-task contention. More...
