Updated code snippet below, OK?

void bg(void)
{
        int i, fdmax;
        /* Simple fork to run proces in the background. */
        switch(fork())
        {
                case 0:
                        break;
                case -1:
                        perror("fork failed"); exit(1);
                default:
                        exit(0);
        }

        if (-1==setsid()) {
                perror("setsid failed"); exit(1);
        }

        /* Close probably all file descriptors */
#ifdef __USE_BSD
        if ((fdmax = getdtablesize()) == -1) exit(1);
#else
        if ((fdmax = sysconf(_SC_OPEN_MAX)) == -1) exit(1);
#endif
        for (i = 0; i<fdmax; i++)
                close(i);

        /* Be nice to umount */
        chdir("/");
}
