Some systems supply a daemon function for running a process in the background.

#include <unistd.h>
int daemon (int nochdir, int noclose);

If the parameter nochdir is zero, the function changes the directory to "/",
otherwise it stays in the current working directory.

The noclose parameter, if zero, directs stdin, stdout, and stderr to /dev/null.

When in doubt, search your man pages for this function.
