| if( listen(s, 10) ) {
| syslog(LOG_ERR,"Can not listen on the socket. %s(%d)",
| strerror(errno), errno);
| exit(1);
| }

| I'm somewhat of a newbie to all this stuff (including sockets) so I
| question why the listen return is being checked for a 1 for error when
| the man pages say -1 is returned on error and 0 is returned on success.
If I'm not totally wrong, only "0" is treated as false, why all non-zero
values are treated as "true", so the comparison is true for -1...
greetings,
~ Lars
