CBaseAllocator::NotifySample

The NotifySample method releases any threads that are waiting for samples.

Syntax

  void NotifySample(void);

Remarks

When there are threads waiting for samples, the value of CBaseAllocator::m_lWaiting is greater than zero. If m_lWaiting is greater than zero, this method calls the ReleaseSemaphore function on the CBaseAllocator::m_hSem semaphore, activating any waiting threads. It also resets m_lWaiting to zero.

This method is called from within the CBaseAllocator::ReleaseBuffer method, when a sample is returned to the free list; and from the CBaseAllocator::Decommit method, when the allocator is decommitted.

Requirements

**  Header:** Declared in Amfilter.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
