Remove trailing whitespace; sort errors; spell "variadic" like
Wikipedia or GNU libc.

Make the ioctl prototype reflect reality and explain why. Also mention that
the generic file descriptor manipulation ioctls are superceded by the
equivalent fcntl one.

Correctly spell 'acknowledged'.

Bump date for FIONWRITE and FIONSPACE.

Add support for FIONWRITE and FIONSPACE ioctls. FIONWRITE reports
the number of bytes in the send queue, and FIONSPACE reports the
number of free bytes in the send queue. These ioctls permit applications
to monitor file descriptor transmission dynamics.

In examining prior art, FIONWRITE exists with the semantics given
here. FIONSPACE is provided so that programs may easily determine how
much space is left in the send queue; they do not need to know the
send queue size.

The fact that a write may block even if there is enough space in the
send queue for it is noted in the documentation.

FIONWRITE functionality may be used to implement TIOCOUTQ for Linux
emulation - Linux extended this ioctl to sockets, even though they are
not ttys.

\- 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.

FIONASYNC should be FIOASYNC

Merge the nathanw_sa branch.

- document generic ioctls.
- mention EFAULT.

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

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

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.

argument is void *, not char * (at least, to the extent that it is a pointer.

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.

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

Use "Er" for argument to -width in the lists in the ERROR sections --- so
the formatting is consistant.

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.

Add RCS indentifiers.
