Here are simulated efuns (=simulated External FUNctionS), marcros and other useful functions defined in daemons: - These simulated efuns are not implemented in C in the GameDriver (GD), but in LPC and located in sys/library , mostly. You can use them like normal efuns, without either calling them in sys/library or including or inheriting sys/library. - Those MACROs (in UPPER CASE below) are "#define"s in /include/auto.h which is included by every object AUTOmatically. - And some useful functions are in defined in a daemon. Call them as described in the corresponding page. See also: efun/, lib/MACROs
