Service Installation in the Winsock SPI (Windows Embedded CE 6.0)
1/6/2010
When the required service class does not already exist, a namespace SPI client uses NSPInstallServiceClass to install a new service class by supplying a service class name, a GUID for the service class identifier, and a series of WSANSCLASSINFO structures. These structures are each specific to a particular namespace, and supply common values such as recommended TCP port numbers or Netware SAP Identifiers.
