The origin is lost in the mists of time --- regproc dates back to
Berkeley times, and the rest of those were named on its precedent.
I've always supposed that it meant "registered", as in "entered in
the system catalogs", but I wasn't there when regproc was invented.
I wonder if there's any evidence for that ... [ digs ] ... ah-hah,
