INFO: Additional Information About GetTypeByName (138038)
The information in this article applies to:
- Microsoft Win32 Software Development Kit (SDK) 3.51
- Microsoft Win32 Software Development Kit (SDK) 4.0
This article was previously published under Q138038 SUMMARY
GetTypeByName takes a service name in string format and returns a global
unique identifier (GUID) for it. GetTypeByName is documented in the Win32
SDK. This article is an addendum to the documentation.
MORE INFORMATION
The purpose of GetTypeByName is to retrieve a GUID of a service. It does
this first by examining the registry, looking for a local service. If the
key does not exist, the function conducts a search of well-known TCP and
UDP service types. If the service GUID is still unknown, a final comparison
is made against a hard-coded list. See Srvguid.h for a list of most of the
known GUIDs.
All comparisons made by GetTypeByName are case-sensitive.
GetTypeByName is exported from Wsock32.dll. To use it for anything other
than registry information retrieval, call WSAStartup first. If WSAStartup
is not called prior to calling GetTypeByName, the function fails, and
GetLastError returns ERROR_SERVICE_DOES_NOT_EXIST, not WSANOTINITIALIZED.
