GetTypeByName - Sockets 2 Reference

GetTypeByName

Important 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 This function is obsolete.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, the reference material is below.

In Windows Sockets 2, this functionality is realized with the functions detailed in Protocol-Independent Name Resolution.

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

INT GetTypeByName(

LPTSTR lpServiceName,	// points to the name of the network service
PGUID lpServiceType	// points to a variable to receive network service type
);

Parameters
lpServiceName

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

lpServiceType

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

Return Values
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. GetLastError may return the following extended error value:
