ITypelib2::GetDocumentation2

[Lost User]

According to MSDN (October 2000), ITypelib2::GetDocumentation2 "will call _DLLGetDocumentation in the specified DLL to retrieve the desired Help string, if there is a Help string context for this item." Unfortunately, I cannot find a function prototype for DLLGetDocumentation() and my searching has devolved into curses! Does anyone know the prototype or where I can find it? Cheers!
