This isn't an accurate comment about HP-UX 10.x and the state of
its proc structure definition.

HP-UX 10.0 does have a struct proc definition in <sys/proc.h>.
The definition disappears at HP-UX 10.10.

I don't believe it was the top author who invented a private proc
struct definition, it was the lsof author.

The current HP-UX 10 machine module in the 3.4 top sources from
eecs.nwu.edu:pub/top (dated August 29, 1996) doesn't seem to support
HP-UX 10.10 or 10.20; at least it has no private proc structure
definition, yet uses ``struct proc'' in several places.

The serious HP user can get a full proc structure definition via
Q4.
