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.
