/****************************************************************
*
* TCPIP.H - Portable TCP/IP header file
*
* TCP/IP on OS/2 is an add-on and thus is not fully integrated
* with the operating system. To ensure portability, follow
* these rules:
*
* * Always call SockInit() at the beginning of your program
* and check that it returns TRUE.
*
* * Use SockSend() & SockRecv() instead of read(), write(),
* send(), or recv() when working with sockets.
*
* * Use SockClose() instead of close() with sockets.
*
* * Use SOCK_ERRNO when using functions that use or return
* sockets, such as SockSend() or accept().
*
* * Use HOST_ERRNO when using gethostbyname() or gethostbyaddr()
* functions.
*
* * As far as I can tell, getservbyname() and related functions
* never set any error variable.
*
* * Use SockStrError() & HostStrError() to convert SOCK_ERRNO
* and HOST_ERRNO to error strings.
*
* * In .MAK files, include $(TCPIP_MAK) & use $(TCPIPLIB)
* when linking applications using TCP/IP.
*
