RtGetCountFastSemaphore returns the number of threads waiting on this fast semaphore. This information is useful when preparing for a manual release of the fast semaphore.
Syntax

)Parameters
pSemaphore
A pointer to a user allocated PRTFAST_SEMAPHORE structure.
pCount
Current count of fast semaphore waiters.
Return Value
If the function succeeds, it returns TRUE. If the function fails, it returns FALSE.

Remarks
A fast semaphore provides signaling functionality without relying on the process thread library. This fast semaphore does not require threads to wake up, resulting in shorter latency.
