CBaseAllocator::SetWaiting

The SetWaiting method increments the count of waiting threads.

Syntax

  void SetWaiting(void);

Remarks

This method increments the CBaseAllocator::m_lWaiting member variable. If a thread is blocked in the CBaseAllocator::GetBuffer method, the allocator calls SetWaiting and then waits for the CBaseAllocator::m_hSem semaphore to be signalled. The CBaseAllocator::ReleaseBuffer method signals the semaphore and sets m_lWaiting back to zero.

Requirements

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

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