WSAInstallServiceClass

The Windows Sockets WSAInstallServiceClass function registers a service class schema within a name space. This schema includes the class name, class id, and any name space specific information that is common to all instances of the service, such as the SAP ID or object ID.

INT WSAInstallServiceClass(

LPWSASERVICECLASSINFO lpServiceClassInfo
);

Parameters
lpServiceClasslnfo

[in] Service class to name space specific type mapping information. Multiple mappings can be handled at one time.

See section Service Class Data Structures for a description of pertinent data structures.

Return Values
The return value is zero if the operation was successful. Otherwise, the value SOCKET_ERROR is returned, and a specific error number may be retrieved by calling WSAGetLastError.

Error Codes

WSAEACCESS	The calling routine does not have sufficient privileges to install the Service.
WSAEALREADY	Service class information has already been registered for this service class ID. To modify service class info, first use WSARemoveServiceClass, and then re-install with updated class info data.
