2.3 LPC/Mudlib interafce

There's a lot of stuff you want to do, like handling strings and saving data to files, that's not exactly LPC. It's part of the 'standard function package' that most programming languages sport. This chapter will teach you the basics of how to do all the things you need in order to create LPC objects.

Objects in the game share a certain set of common properties, the ones you always can rely on to be there for any kind of object are these:

The object is created by someone. The identity of this creator is set depending on the file-system location of the source code. If the object resides in the directory of a domain-active wizard, the creator is said to be the name of that wizard. Otherwise the domain name is used. For mudlib objects the creator usually is root for admin objects and backbone for the rest.

The uid (User ID) of an object defines the highest possible privilege level of an object. The uid itself is is only used to affect the euid (Effective User ID) of the same or another object. The euid is later checked in situations where the privilege of the object needs to be examined i.e. file access (reading/writing/removing) and object creation.

In order for an object to be able to receive command-lists or issue commands it has to be living.
