WMCheckURLScheme function (wmsdkvalidate.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The WMCheckURLScheme function examines a network protocol and compares it to an internal list of supported schemes. If you are writing an application that can handle many different network protocols, you can use this function to ascertain quickly whether a network address can be handled using the methods of the Windows Media Format SDK.
