Well, I was just wondering about g_spawn_with_pipes.. I use it to execute
an external program for me.. Under FreeBSD (at least) when it is run at
the same time i got sound playing with a thread through ESD.. the
g_spawn.. seems to block the main process.
The only solution I found to make it stop blocking was with some code
similar to the following:
if (fork() == 0) {
register int cnt;
/* close all the fds in the child to prevent it from hogging thea udio
device */
for (cnt = 3; cnt < 255; cnt++)
close(cnt);
exec...
_exit(0);
}
and well, now it does not block. I was just wondering if there is some
similar code in the gspawn part in the glib, but I have not checked
myself. I think there should be something like this, since this forked
child should not need those fds anyway..
Sincerely,
Gunnsteinn Hall
