  Hello world.  I am trying to incorporate socket call in a 'C' program written
  for Windows 3.0.  The program aborted once it use the socket call statement.  
  What I have on my PC is Windows 3.0 SDK, SUN PC-NFS Programmer's Toolkit 
  Version 1.00, and Microsoft 'C' 5.1.

  Is there any way I could make the socket system call works under Windows 3.0.

I've been able to get this to work, but only with great pain.  The trick
is to make a TSR which holds the PC-NFS code, and call the TSR from Windows.
In order to do that, you have to allocate a buffer with GlobalDOSAlloc,
copy all the arguments into that buffer, call the TSR, copy all the return
values back into the buffer, and return to Windows.  It's a lot of work,
very hard to get right, and it's very slow.

I haven't found other vendors yet with socket libraries for Windows.
I saw an ad for some company, but it wasn't yet released and had high
per-user royalties.

If there's a better way, I'd sure like to know about it.
