CreatePosPassThru

  • Article

STDAPI CreatePosPassThru(
  LPUNKNOWN pAgg,
  BOOL bRenderer,
  IPin* pPin,
  IUnknown** ppPassThru
);

Parameters

  • pAgg
    NULL if the object is not being created as part of an aggregate; otherwise, a pointer to the aggregate object's IUnknown interface (the controlling IUnknown).
  • bRenderer
    TRUE if the filter supports rendering; otherwise, FALSE.
  • pPin
    Pointer to the filter's input pin.
  • ppPassThru
    Address of a pointer to an ISeekingPassThru interface.

Return Values

Returns S_OK if successful; otherwise, returns an HRESULT indicating the error.

Remarks

You can use this function to create a CPosPassThru object in Quartz.dll rather than from your own .dll file. The CLSID of the object is CLSID_SeekingPassThru.

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.
