They only exist on Micro$oft-ish so called "operating systems". If you try
to use libwww on a *ix [Looking at your e-mail address, I guess you use
HP-UX], you won't have them.

Strange, I did it just like that. I guess you are just "read"-ing the data
you sent to the socket in your Event callback - you shouldn't do anything
else, I guess.

Have you tried to communicate with socket between different threads
before, without libwww? Maybe there is some more fundamental problem
lurking around.

You may also use a tool like strace (if something like this exists on your
system) to trace the system calls your program uses. You should see
the socket to be included in the fd_sets of a select() system call.
