CBaseMediaFilter::GetState

  • Article

Retrieves the current state of the filter.

HRESULT GetState(
  DWORD dwMilliSecsTimeout,
  FILTER_STATE* State
);

Parameters

  • dwMilliSecsTimeout
    Duration of the time-out, in milliseconds.
  • State
    Returned state of the filter.

Return Values

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.

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.
