CBaseInputPin.BreakConnect method

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The BreakConnect method releases the pin from a connection.

Syntax

HRESULT BreakConnect();

Parameters

This method has no parameters.

Return value

Returns S_OK if successful, or an HRESULT value indicating the cause of the error.

Remarks

If you override this method, call the base-class method from your overriding method. Otherwise, you might cause memory leaks.
