Semaphore Class Reference

Abstraction of a semaphore. A semaphore object is a synchronization object that maintains a count between zero and a specified maximum value. The count is decremented each time a thread completes a wait for the semaphore object and incremented each time a thread releases the semaphore. When the count reaches zero, no more threads can successfully wait for the semaphore object state to become signaled. The state of a semaphore is set to signaled when its count is greater than zero, and nonsignaled when its count is zero. More...

Detailed Description

Abstraction of a semaphore. A semaphore object is a synchronization object that maintains a count between zero and a specified maximum value. The count is decremented each time a thread completes a wait for the semaphore object and incremented each time a thread releases the semaphore. When the count reaches zero, no more threads can successfully wait for the semaphore object state to become signaled. The state of a semaphore is set to signaled when its count is greater than zero, and nonsignaled when its count is zero.

Constructor & Destructor Documentation

Semaphore

(

Int32

initialCount

)

Constructor.

Parameters

initialCount

Initial value of the semaphore. maxCount limit fixed at MaxInt32

Semaphore	(	Int32	initialCount,
		Int32	maxCount
	)

Constructor.

Parameters

initialCount	Initial value of the semaphore.
maxCount	Maximum value of the semaphore.

Semaphore	(	PCChar8	name,
		Int32	initialCount,
		Int32	maxCount
	)

Constructor.

Parameters

name	The name.
initialCount	Initial value of the semaphore.
maxCount	Maximum value of the semaphore.

Warning

Non-Deterministic. Determinism when using ConceptRT library can be ensure by using Context Time Critical mechanisms.
