introduce a couple of new turn-off-gcc-warning variables and use them.

GCC 14 has a new annoying calloc() checker that we turn off in a bunch
of places, and there are a few more dangling-pointer issuse that come up,
but seem bogus.

introduce new GCC 12 warning disables and use them in a few places

this introduces 4 new warning disable flags:

CC_WNO_MISSING_TEMPLATE_KEYWORD
CC_WNO_REGISTER
CC_WNO_STRINGOP_OVERREAD
CC_WNO_ARRAY_BOUNDS

and documents them in README.warnings. of these, the string op
and array bounds are both problematic (real bugs) and also spurious
(not real bugs), and the other 2 are mostly temporary for older
3rd party code.

add some new uses of CC_WNO_STRINGOP_OVERFLOW.

fix m68k build for gallium and GCC 12.

install prenice(1) and man page links.

Fix sign-compare issues

branches: 1.2.30;
WARNS=3 and remove default values.

pgrep and pkill: search the process table for processes with a particular
set of characteristics, and either print or signal the matching set. Mostly
compatible with the Solaris commands of the same name.

pkill(1): Add -F option to use a pidfile and -L to ensure it's locked

Taken from FreeBSD

branches: 1.32.4;
Add a -q option for pgrep to not print anything; similar to grep -q.

s/implemenation/implementation/ in comment.

Sort SEE ALSO.

Note these tools use kvm(3) and not procfs as in Solaris.

branches: 1.28.2; 1.28.4;
Add pgrep and prenice to the NAME section

Add AUTHORS section
bump date

Document that patterns are specified using extended regular expressions.

Formatting fix.

prenice (like pgrep and pkill) won't match itself. Also fix nearby typo.
Bump date. From Ted Unangst in PR 47880.

branches: 1.23.6; 1.23.12;
Fix SYNOPSIS; pkill accepts -l options since 3 years ago. `pattern' is
mandatory for all commands and `priority' is mandatory for prenice.

Be explicit which options are available for prenice. Bump date.

add -l support to prenice, as noted by enami.

Bump date for prenice, add serial comma, and fix an xref.

add a "prenice <priority> <names>" command.
use it like "prenice -4 mplayer".

Drop trailing whitespace.

Handle ptyfs ptys. Should probably pull up to 5.

branches: 1.16.8;
Convert TNF licenses to new 2 clause variant

branches: 1.15.10;
Allow the -l (long format) option to be used with pkill too.

Remove authors section, and update history where appropriate.

Fix cross-reference to grep(1).

Wording, use more macros, xref grep(1). From jmc@openbsd.

Sort options; from jmc@openbsd.

Bump date for -i.

Add a -i option to ignore case in the process match.

The correct capitalisation of 'NetBSD.org' is (you
guessed it) 'NetBSD.org'.

some mdoc fixes.

- System processes will never be matched.
- A dash given to `-t' matches processes with no controlling terminal.

Solaris 2.7 -> 7

The first Solaris release with pkill and friends was 2.7.

Add HISTORY section. I _think_ these appeared in Solaris 2.6, please
fix if it's not so.

Fix typo.

A persistent typo, and some minor mark-up improvements.

pgrep and pkill: search the process table for processes with a particular
set of characteristics, and either print or signal the matching set. Mostly
compatible with the Solaris commands of the same name.

pkill(1): Add -F option to use a pidfile and -L to ensure it's locked

Taken from FreeBSD

branches: 1.33.4;
Add a -q option for pgrep to not print anything; similar to grep -q.

Cosmetic tweak. No functional change.

PR bin/50934 -- avoid core dump if a process being examined has set
its argv[0] to NULL.

XXX Needs pullups netbsd-7-0 and netbsd-7 (bug was introduced after
netbsd-6 and never pulled up, so no netbsd-6 pullups required.)

branches: 1.30.2; 1.30.4;
Simplify code so that gcc 4.8 can understand it.
http://mail-index.netbsd.org/tech-userlevel/2015/01/06/msg008882.html

branches: 1.29.8;
Explicitly include sys/resource.h

Don't use p_comm since it is only 16 characters long and you can find the
full argv[0]. It is just confusing to have a long command name, that ps
shows as the long command name, and then when you try to kill it using
the full command name as displayed you don't get a match. While there
fix a format nit, and remove the main() declaration.

branches: 1.27.6; 1.27.12;
add -l support to prenice, as noted by enami.

add a "prenice <priority> <names>" command.
use it like "prenice -4 mplayer".

Fix sign-compare issues

Handle ptyfs ptys. Should probably pull up to 5.

Remove clause 3 and 4 from TNF licenses

convert __attribute__s to applicable cdefs.h macros

branches: 1.21.4;
Allow the -l (long format) option to be used with pkill too.

Revert the changes done after newlock2 merge, except for the removal of
the now unused LSDEAD state. The current kernel headers are now
source-compatible with pre-newlock2 kernel headers again.

Approved by Andrew Doran.

Further changes to use compat process flags mapped by sysctl. To be
revisited soon.

Sync with kernel changes introduced by merging the newlock2 branch.

Sort options; from jmc@openbsd.

Exit with 2 on usage errors as documented. Noted by Christian Biere in
PR bin/21933.

Downgrade failure to kill(2) (other than ESRCH) from fatal error to a
warning; otherwise processing aborts and possibly matching killees would
remain unsignalled. This makes pkill match the Solaris behavior.

Sprinkle const liberally

From discussion on tech-userlevel, change the comment formatting in the
changes applied in revision 1.10. At the same time, expand the comments
a bit to make the code slightly clearer. No code changes.

Fix more lint problems.

- KNF
- better handling of errors and messages
- pass lint

From David Sainty: If a process dissappears while we are signalling it, don't
count it as a match/error.

branches: 1.9.2;
Add a -i option to ignore case in the process match.

If a user or group is not known, report the problem user/group, rather than
the first user/group. Caused huge fun in error messages from large script.
Old: pgrep -u root,NoSuchUser,daemon -> pgrep: unknown user `root'
Now: pgrep -u root,NoSuchUser,daemon -> pgrep: unknown user `NoSuchUser'

branches: 1.7.4;
Make usage() not overflow 80 char lines.

typo fix. do not go suicide by mistake. from millert@openbsd

Add missing -u euid option to optstring; from Michael van Elst in
PR bin/18827.

branches: 1.4.2;
Exclude system processes when the match is inverted.

Fix 3 bugs in signal number decoding:
* invoking pkill without any arguments gave a core
* an initial numeric prefix of a signal name was ignored, e.g. -88sigint
* argc was not updated when the signal number was decoded.
