I just recently started playing with an application that was written
originally on SunOS 4.1.3 and I ported it to FreeBSD 2.2.1 and
everything was fine. I upgraded to 3.0 and now I experience problems
apparently caused by using the notify_do_dispatch() call and ANY
subsequent file I/O. I went ahead and attached the sample program that
demonstrates this oddity, in case anyone wants to help me locate its
source/cure. I compile it as follows:
gcc -o main main.c -I/usr/X11R6/include -g -L/usr/X11R6/lib -lxview
\ -lX11 -lolgx
Any help would be appreciated!
Ed
