Type something, I guess. 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.
