I don't think it derives from "master/slave network architecture.”.  I think it 
derives from the use of “master”
to denote an instance or prototype that is used to create identical copies or 
replicas, a usage that predates networking, as in master tape, master print, 
and, (perhaps archaically for you :)), mimeograph master.

Irrelevantly, I also think all (almost all?) uses of "master/slave” to describe 
network architectures are lazy; there is a better existing description, e.g. 
“active/passive”, “polling” etc.

P.S. My preference would be “mainline” over “main”.  I like railroad version 
diagrams.

I think it's just short for "type". There's an old tradition
in C of giving member names a short prefix reminiscent of
the type they belong to. Not sure why, maybe someone thought
it helped readability.


In early ages of C structures didn't create namespaces, and member names were globals.That's nonsense. The reason is greppability. Nonsense is a little harsh :).  Global member names aren’t why you used prefixes, but early C has them.I burned my fingers on them as a small programmer on this.  Sometime before 1980.
