HRESULT QueryPinInfo(
  PIN_INFO* pInfo
);

Parameters

  • pInfo
    Pointer to a PIN_INFO structure.

Remarks

This member function implements the IPin::QueryPinInfo method. By default, the member function fills in the PIN_INFO structure with the IBaseFilter interface of its owning filter, the pin name from m_pName, and the pin direction from m_dir.

The IBaseFilter interface passed out by this member function is reference counted, and so must be released when the caller has finished with it.

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.
