HRESULT QueryId(
LPWSTR
*
Id
);

Parameters

Id
Pin identifier.

Return Values

Returns an HRESULTvalue.

Remarks

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