Yeah! It works. Almost perfect. I just this get the following message:
XIO: fatal IO error 9 (Bad file number) on X server "cobalt.xirion.nl:0.0"
after 1424 requests (1420 known processed) with 0 events remaining.
Can I just ignore it? It looks as if I close the connection with a wrong
number, but I did jst the following:
Display *dpy;
dpy = fl_initialize();
wholelotofwork();
pid=fork();'
if (pid = 1)
{
/* Child */
close(ConnectionNumber(dpy));
somethingelsetobedone;
}
Looks allright to me?
