Oddly enough, -1 means you got an error. There should be a code in errno
specifing exactly what error you got. The information I just gave you, along
with the information you will need to decipher the errno value should be in
your win32 documentation, or a good book on sockets.
As an aside, there's a little-known feature of Gnat that allows you to compile
Ada code with it. You really ought to try it out. ;-)

Take a look at
http://www.botton.com/ada/os
There are some Ada 95 examples of sockets and links to thick bindings
for Win32 and Unix.

Yes.
You need to call WSAStartup before any of the Win32 socket stuff will work
at all.
You'll have to find this in the Win32 documentation since it is Win32
specific (no such call is required under UNIX).

The above program was a C program! Not an Ada 95 program.
GNAT is an Ada 95 compiler, so most certainly you did NOT
compile this using GNAT. The GNAT distribution includes the
GNU C front end for gcc, which provides a standard C
environment, but it has nothing to do with Ada, so your
question is better addressed to a different news group.

: The output was -1.
You might take a look at my sockets package for Win32 on my
homepage.

Jerry.
