class Semaphore
Types 1
classSemaphore
This class represents a general counting semaphore as concieved by Edsger Dijkstra. As per Mesa type monitors however, "signal" has been replaced with "notify" to indicate that control is not transferred to the waiter when a notification is sent.
Fields
Handle m_hndlHandle to the system-specific semaphore.Methods
void wait()Wait until the current count is above zero, then atomically decrement the count by one and return.bool wait( Duration period )Suspends the calling thread until the current count moves above zero or until the supplied time period has elapsed. If the count moves above zero in this interval, then atomically decrement the co...void notify()Atomically increment the current count by one. This will notify one waiter, if there are any in the queue.bool tryWait()If the current count is equal to zero, return. Otherwise, atomically decrement the count by one and return true.Constructors
this( uint count = 0 )Initializes a semaphore object with the specified initial count.Destructors
