CRendererInputPin::QueryId (Windows CE 5.0)
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 Win32 CoTaskMemAlloc function to initialize Id, so the user is responsible for freeing the format block by using CoTaskMemFree.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
