These are cTypes for Category "Intelligent Bus". We wanted to differentiate between intelligent busses, such as SCSI and other busses such as VME. As developers choose types for the categories
Intelligent Bus and Bus, we will update the cTypes appropriately.
It is important to note that the most important thing is to have unique identifiers for functions
(in fact, the sRsrc_Type is really just a big long integer, that is subdivided into hierarchical subtypes in order to group functions in a better way). When the slot manager is used to locate a function, the approprate Category/cType/DrvrSW/DrvrHW values are used to pack or fill in the sRsrc_Type longint. What this means is that, once an application knows the values for a particular sRsrc_Type that it is interested in, it can look for them, and there can be more than one sRsrc_Type that it may wish to look for.
