Chris,
Thanks for the info. I looked at my code, though and
it looks exactly like your snippet.
Did you actually try that? If it works like mine, your
NetLibSelect() will return immediately whether you have
a pending connection or not .... sigh.
As a matter of fact, if you have a loop executing your
snippet, it will return immediately *every* time - making
NetLibSelect() pretty useless for this purpose.

Take a look at Jim Rees' httpd code or if you have it, CW comes with an ftp
server that does a lot of that stuff. However, httpd uses a lot of blocking
stuff, and in fact it just sits on a blocking accept() IIRC. But it may
help
you find a problem in your code if you look at the other stuff he does.

If you are using NetLibSelect() to wait for a connection request then IIRC
it will appear as a read, so just do something like this:
netFDZero(&rfds);
netFDZero(&wfds);
netFDSet(sysFileDescStdIn, &rfds); /* if you want system events */
netFDSet(listensocket, &rfds);
rv = NetLibSelect(AppNetRefnum, netFDSetSize, &rfds, &wfds, NULL,
to, &errno);
if (rv > 0) {
if (netFDIsSet(listensocket, &rfds)) {
/* accept the connection into another socket */
}
}
