You do know that you usually don't have a /home/ directory on Mac OS X?
On Mac OS X it's called /Users/.
BTW, running that on Mac OS X 10.6.3 does not cause a crash. Although it
doesn't seem to print or write anything.

You do know that you usually don't have a /home/ directory on Mac OS X? On Mac OS X it's called /Users/.Yeah, that was me running the same code on Ubuntu.BTW, running that on Mac OS X 10.6.3 does not cause a crash. Although it doesn't seem to print or write anything.That's the problem i can't pin down. It writes the above log file to /var/log/system.log. other than that there is no feedback at all, the program just ends without writing to the open file. It seems to be related to the daemon code as it doesn't happen when that code is commented out.

In fact i have the same problem reading files too. It only reads files up to a certain amount of bytes then crashes in the same manner explained above. Again this only happens when the program runs as a daemon.

"Gary Willoughby" <Dev kalekold.net> Run as a daemon how?By running the above code. All the code before opening the file causes the program to run as a daemon.
