CBasePin::Inactive

  • Article

Switches the pin to an inactive state.

virtual HRESULT Inactive(void);

Parameters

None.

Return Values

Returns NOERROR for a base class implementation. The overriding member function returns a standard HRESULT value and should not fail if the pin is already set as inactive.

Remarks

This member function is called by the IMediaFilter implementation when the state changes to inactive. This member function should be overridden to decommit allocators and free any hardware resources that were obtained in the CBasePin::Active call. The default implementation of the base class member function does nothing.

Note that the filter graph manager's internal state variable is not updated until after this member function returns, so testing the filter graph manager's state (directly or indirectly) from within this member function should be avoided.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
