//  TCPCMN.H - central header file for TCP/IP structures and configuration
//         functions
//

//  HISTORY:
//  
//  12/6/94    jeremys  Created.
//  96/03/23  markdu  Removed Get/ApplyInstanceTcpInfo functions.
//  96/03/23  markdu  Removed TCPINFO struct and TCPINSTANCE struct.
//  96/03/25  markdu  Removed connectoid name parameter from 
//            Get/ApplyGlobalTcpInfo functions since they should not
//            be setting per-connectoid stuff anymore.
//            Renamed ApplyGlobalTcpInfo to ClearGlobalTcpInfo, and 
//            changed function to just clear the settings.
//            Renamed GetGlobalTcpInfo to IsThereGlobalTcpInfo, and
//            changed function to just get the settings.
//            Removed TCPGLOBAL struct,
//  96/04/04  markdu  Added pfNeedsRestart to WarnIfServerBound, and
//            added function RemoveIfServerBound.
