RtReleaseAllFastSemaphore

RtReleaseAllFastSemaphore releases all threads waiting on the fast semaphore. Ensures that all waiting threads enter the ready-to-run state. Ensures that no new threads enter the busy wait state until all current waiters have become runnable.

Syntax

BOOL RtReleaseAllFastSemaphore(
    [in]    PRTFAST_SEMPHORE pSemaphore
)

Parameters

[in] pSemaphore

A pointer to a user allocated RTFAST_SEMAPHORE structure.

Return Value

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. Call GetLastError to obtain an error code.

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.
