Increments the m_lWaitingdata member to indicate that a thread is waiting for a sample.
Syntax
void SetWaiting( ); |
Parameters
None.
Return Value
None.
Remarks
This member function is called from CBaseAllocator::GetBufferif no samples are available on the free list.
After calling this, CBaseAllocator::GetBuffercalls the Win32 WaitForSingleObjectfunction to wait for the list to signal that a sample is available.
The list signals by calling CBaseAllocator::ReleaseBuffer, which in turn calls CBaseAllocator::NotifySample, which sets m_lWaitingto zero and calls the Win32 ReleaseSemaphorefunction.
