CPullPin.BeginFlush method

The BeginFlush method informs the owning filter to flush the downstream filters. The derived class must implement this method.

Syntax

virtual HRESULT BeginFlush();

Parameters

This method has no parameters.

Return value

Returns an HRESULT value.

Remarks

The CPullPin::Seek method calls this method. Implement this method to call the IPin::BeginFlush method on each downstream input pin that receives data from this object. If your filter's output pin(s) derive from CBaseOutputPin, call the CBaseOutputPin::DeliverBeginFlush method.

This design enables the filter to seek the stream simply by calling Seek on the CPullPin object.
