GetTypeByName function

The GetTypeByName function retrieves a service type GUID for a network service specified by name.

Note  The GetTypeByName function is a Microsoft-specific extension to the Windows Sockets 1.1 specification. This function is obsolete. For the convenience of Windows Sockets 1.1 developers, this reference material is included. The functions detailed in Protocol-Independent Name Resolution provide equivalent functionality in Windows Sockets 2.
