CBaseAllocator::SetWaiting

  • Article

Increments the m_lWaiting data member to indicate that a thread is waiting for a sample.

void SetWaiting( );

Parameters

None.

Return Values

None.

Remarks

This member function is called from CBaseAllocator::GetBuffer if no samples are available on the free list. After calling this, CBaseAllocator::GetBuffer calls the Win32 WaitForSingleObject function 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_lWaiting to zero and calls the Win32 ReleaseSemaphore function.

Requirements
