The lxidef.h header contains the item type, item channel and item channel definitions for the built-in item types. For the most part the definitions are here, although in some cases they exist in other more specific headers. In all cases the defintions follow a simple format.
- LXsITYPE_typename -- the name of the item type
- LXsICHAN_typename_channelname -- the name of a channel for the item type
- LXsICVAL_typename_channelname_value -- an integer channel value hint
