IPin::Disconnect method (strmif.h)

The Disconnect method breaks the current pin connection.

The Filter Graph Manager calls this method when it disconnects two filters. Applications and filters should not call this method. Instead, call the IFilterGraph::Disconnect method on the Filter Graph Manager.
