branches: 1.39.14; 1.39.16;
Whitespace.

Add crossreference to fork(2) per note in PR 9627.

Document WNOZOMBIE

branches: 1.36.2;
Document WAIT_ANY and WAIT_MYPGRP constants
(text referenced from OpenBSD wait(2) man page)

While there, remove duplicated information and add more refernces in SEE ALSO
Also, the NOTES section refers to intro(2), while siginterrupt(3) is a better
suited reference, so fix that too.

Ok by wiz

move section around.

Sort a bit more.

- merge the options descriptions, sort them.
- fix wrusage name.

Drop trailing whitespace.

revert part of previous; not needed.

- clarify si_signo difference for waitid and wait6 as per POSIX.
- implement it.
- document WIFCONTINUED

Use more markup, fix a typo.

userland bits for wait6/waitid.

The functions read(), wait(), and write() appeared already in v2 UNIX.

Put the description of "options" in a new paragraph, for consistency

\- is a minus, not -.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Use
.In header.h
instead of
.Fd #include \*[Lt]header.h\*[Gt]
Much easier to read and write, and supported by groff for ages.
Okayed by ross.

Merge the nathanw_sa branch.

Drop trailing whitespace.

Explain how WIF* macros use the status value instead of the pointer to the status value as wait() does. We use the name 'status' both as the argument to wait() and WIF* macros, this is misleading.

New sentence, new line. From Robert Elz.

Remove <sys/types.h> from synopsis, as per latest SUS/Posix specs.

Generate <>& symbolically. I'm avoiding .../dist/... directories for now.

Sort sections, sort SEE ALSO, punctuation and miscellanous fixes.

Boring whitespace fixes.

Don't need <sys/types.h> or <sys/time.h> before <sys/resource.h>.

Document WALTSIG (and __WCLONE) and WALLSIG (__WALL). Restructure the
options documentation to make it easier to read.

branches: 1.12.6;
Add a LIBRARY section to system call manual pages. While it's clear that the
libraries contain stubs only (with minor exceptions a la pipe(2)), the purpose
of this section is to provide linkage information.

branches: 1.11.6;
Last of the .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages. Wheee!

first pass at fixing up capitalization of function names and
arguments; ensure that each is correct with respect to the
implementation, rather than being correct as per english.

Add missing `STANDARDS' compliance statements. As we #define _POSIX_VERSION
to 199009L, bump existing statements to 1003.1-1990.

xref _exit(2) or exit(3) instead of exit(2)

check options argument to wait{3,4,pid}(); from Klaus Klein in PR 3182.

merge with lite, keeping most local changes. clean up Ids

Fix spelling errors.

Clean up manpages:
Use .Fn rather than .Nm macro in HISTORY and STANDARDS sections.
Use .At and .St macros instead of spelling out "Version 6 UNIX",
"IEEE 1003.1-1988 (POSIX)", etc.

Changed SYNOPSIS. Moved function "prototype" for waitpid above #include
of <sys/reso

Add RCS indentifiers.
