DECnet-Specific Extended Functions Identifiers

This section presents the DECnet-specific extensions to the Windows Sockets 2 specification.

The Windows Sockets 2 function extension mechanism works as follows: a call is made to WSAIoctl with the control code SIO_GET_EXTENSION_FUNCTION_POINTER that returns a function pointer to a specified extension function.

The following DECnet-specific extension identifiers have been allocated by the WS2 identifier clearinghouse.

Note  We reserve 32 in each block.
