Add an ioctl to return channel number (AUDIO_GETCHAN). This can be used
on audio/sound/audioctl devices.
Return EIO in read/write/ioctl/poll/stat if fp has been closed or is
invalid.
Update audio.4, audioio.h and audioctl(1) to reflect these changes.
PRIxOFF (and PRIdOFF) to print off_t's in a way that matches the
arch's definition of off_t.
In the meantime fall back on %jx and an (intmax_t) cast. Ugly.
(And the way it is written is even uglier...)
- committed separately to make it easier to swap back if desired.
This version avoids open coding is_name() and isdigit() - measurements
show it is perhaps fractionally faster (though the difference is so small
as to probably be statistically insignifigant - if I were a statician
I might understand that) and just a little larger than the previous version.

That meant adding the assignment operators ('=', and all of the +=, *= ...)
Currently, ++, --, and ',' are not implemented (none of those are required
by posix) but support for them (most likely ',' first) might be added later.
To do this, I removed the yacc/lex arithmetic parser completely, and
replaced it with a hand written recursive descent parser, that I obtained
from FreeBSD, who earlier had obtained it from dash (Herbert Xu).
While doing the import, I cleaned up the sources (changed some file names
to avoid requiring a clean build, or signifigant surgery to the obj
directories if "build.sh -u" was to be used - "build.sh -u" should work
fine as it is now) removed some dashisms, applied some KNF, ...
Why is there no PRI[xd]OFF ? How are off_t's intended to be printed?
If a PRIxOFF gets added in some appropriate place, the XXX lines in this
commit can go away.
(I understand not having PRI[xd]VOFF).
- Extend alldevs_mtx section in deviter_init.
- Assert ownership of alldevs_mtx in private functions:
. deviter_reinit
. deviter_next1
. deviter_next2
- Acquire alldevs_mtx in deviter_next.
(alldevs_mtx is not relevant to the struct deviter object, which is
private to the caller who must guarantee exclusive access to it.)
Add 5 new test cases to test various ways that $* can be expanded.
Currently 3 of the 5 are marked as "expected to fail" because of the
bug in this PR.
