We now do ARP checking by default as recommended by RFC 2131. Add RFC 3927 (aka IPV4LL aka APIPA) support by default. 2007-07-18 19:26:59 +08:00			`#ifdef __linux__`

Many thanks to Michael Durrant for testing the below changes. Compile and work on OSX/Darwin. If we have no fork then we re-exec ourselves with --daemonised. Improved the build system so we automatically detect if we need librt or libresolv and if fork() works or not. Move back to using librt for clock_gettime on Linux systems. 2007-09-04 20:48:40 +08:00			`void close_fds (void);`
Suck it hard and use gettimeofday for Linux. Lets just hope that the clock works under Linux during ARP floods. 2007-08-21 17:50:01 +08:00			`int get_time (struct timeval *tp);`
timeval defines seconds as long, so we should use long over time_t 2007-11-08 04:59:52 +08:00			`long uptime (void);`
Write the pidfile before we fork so we can easily be stopped by other processes. 2007-10-21 00:58:13 +08:00			`void writepid (int fd, pid_t pid);`

Send a FQDN hostname if it contains dots, strip the domain from a looked up hostname if it matches our domain or search and sanitize our fd's a little better. 2007-04-27 00:16:56 +08:00			`char xstrdup (const char str);`
Add safe_strncpy function to ensure everything is NULL terminated 2007-04-06 00:56:58 +08:00
