The ptid_t contructors, accessors and predicates are documented in
_three_ places, and each place uses a different wording.
E.g, the descriptions in the .c file of the new ptid_lwp_p, ptid_tid_p
weren't updated in the final revision like the descriptions in the .h
file were. Clearly, switching to a style that has a single central
description avoids such issues.
Worse, some of the existing descriptions are plain wrong, such as:
/* Attempt to find and return an existing ptid with the given PID, LWP,
and TID components. If none exists, create a new one and return
that. */
ptid_t ptid_build (int pid, long lwp, long tid);
The function does nothing that complicated. It's just a simple
constructor.
So this gets rid of all the unnecessary descriptions, leaving only the
ones near the function declarations in the header file, and
fixes/clarifies those that remain.
