Notifies a waiting thread that a sample is available on the free list.
Syntax
void NotifySample(void);
Parameters
None.
Return Value
None.
Remarks
If m_lWaiting has been incremented (is not zero), this indicates a thread is waiting.
This member function checks for this condition and calls the Win32 ReleaseSemaphore function with the semaphore value m_hSem to activate any waiting thread.
It also sets m_lWaiting back to zero.
This member function is called from CBaseAllocator::ReleaseBuffer when putting a sample back on the free list and from CBaseAllocator::Decommit when decommitting the allocator (so that waiting threads can be denied).
