RtGetCountFastSemaphore

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

BOOL RtGetCountFastSemaphore(
    CONST PRTFAST_SEMAPHORE pSemaphore, 
    PULONG pCount
)

Parameters

pSemaphore

A pointer to a user allocated PRTFAST_SEMAPHORE structure.

pCount

Current count of fast semaphore waiters.

Return Value

TRUE if the function succeeds, FALSE if the function fails

To get any extended error information, call GetLastError().

Remarks

A fast semaphore provides signaling functionality without relying on the RTSS thread library. The result is shorter latency as use of this fast semaphore does not require the waking up of threads.
