GetTypeByNameW function (nspapi.h)

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 This function is obsolete.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.

 

Syntax

INT GetTypeByNameW(
  [in]      LPWSTR lpServiceName,
  [in, out] LPGUID lpServiceType
);

Parameters

[in] lpServiceName

A pointer to a zero-terminated string that uniquely represents the name of the service. For example, "MY SNA SERVER."

[in, out] lpServiceType

A pointer to a variable to receive a globally unique identifier (GUID) that specifies the type of the network service. The Svcguid.h header file includes definitions of several GUID service types and macros for working with them.

The Svcguid.h header file is not automatically included by the Winsock2.h header file.

Return value

If the function succeeds, the return value is zero.

If the function fails, the return value is SOCKET_ERROR( – 1). To get extended error information, call GetLastError, which returns the following extended error value.

Value	Meaning
ERROR_SERVICE_DOES_NOT_EXIST	The specified service type is unknown.

Remarks

Note

The nspapi.h header defines GetTypeByName as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
