I would but the author of Schrodinger chat was the one who found
the problem since the program loads but just doesn't work the way it's
supposed to as it did in 2.05R. Here's what he said:
On SunOS 4.1.3, solaris, linux, ultrix, irix, ... my chatline
program stayed at the line where select() was when nobody was logged on
or when nobody was typing. It's acts in char mode telnet. On
freebsd-current, it doesn't stay at select() when nobody is logged on or
when nobody is typing.
select line is something like
select((fd_set *)readfds, (fd_set *)0, (fd_set *)0, (time_t *)0);
the file descriptors for each socket is set for i/o non-blocking
with fcntl() ... (can't remember the exact syntax offhand .. I'm on the
fly right now)
(it's something like that ... I don't do unix C programming any longer
.. I'm quoting from memory ... I was forwarded this letter from somebody
using my chatline code).
btw, my chatline program worked "properly" on FreeBSD 2.0.5, 2.0
and previous versions 1.5.1.1 (or whatever version that novell
doesn't want anybody using).
