Retrieves the current state of the filter.
Syntax
HRESULT GetState(
DWORD dwMilliSecsTimeout,
FILTER_STATE* State
);
Parameters
- dwMilliSecsTimeout
Duration of the time-out, in milliseconds.
- State
Returned state of the filter.
Return Value
Returns S_OK.
Remarks
This member function implements the IMediaFilter::GetState method. It returns the value of the m_State data member.
Filters should derive their filters from CBaseFilter and not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::GetState instead.
