** WS2TCPIP.H - WinSock2 Extension for TCP/IP protocols
|

**
|
|
** This file contains TCP/IP specific information for use
|
|
** by WinSock2 compatible applications.
|
|
**
|
|
** To provide the backward compatibility, all the TCP/IP
|
|
** specific definitions that were included in the WINSOCK.H
|
|
** file are now included in WINSOCK2.H file. WS2TCPIP.H
|
|
** file includes only the definitions introduced in the
|
|
** WinSock 2 Protocol-Specific Annex document.
