CRendererInputPin::QueryId

Retrieves an identifier for the pin.

HRESULT QueryId(
LPWSTR *Id );

Parameters

  • Id
    Pin identifier.

Return Values

Returns an HRESULT value.

Remarks

This member function implements the IPin::QueryId method. It overrides the CBasePin::QueryId member function and assigns the string "In" to Id. Note that it uses the Microsoft® Win32® CoTaskMemAlloc function to initialize Id, so the user is responsible for freeing the format block by using CoTaskMemFree.
