  Well you'll need the TCP/IP Developers Toolkit (or whatever it is
  called) which contains the header files and libraries with functions
  for creating and accessing sockets etc, and I think this costs money.
  Or you can download EMX which comes with all that by default, and
  start crunching code right away... EMX is completely free, BTW.

  And it has an advantage over IBM's approach to socket programming
  because it treats socket handles like simple file handles, and you can
  read and write to them simply by using C file I/O functions and wait
  for I/O from them using the select() call just as if they were
  ordinary files or character devices (you can still use the specialized
  socket I/O functions if you like), while the IBM toolkit has a
  separate handle space for sockets (this isn't really such a drawback
  for IBM's toolkit, but I thought I'd mention it anyway).

  OTOH, EMX doesn't provide access to special OS/2 specific high
  performance socket I/O functions (sysctl() to allocate and enable
  special buffers, and then using the MSG_MAPIO flag in send() to
  actually use them), because they aren't found in the standard BSD 4.4
  socket implementation, and therefore are not supported by EMX (which
  strives toward Unix/POSIX compatibility). Once again, this isn't such
  a big drawback for EMX, since the underlying OS/2 TCP stack is very
  optimized, and you'll need a VERY bussy high-throughput server to
  actually see any difference and benefit from using those specialized
  functions.
