Yup, we do:
alx@debian:~$ man -wa timeval
/usr/share/man/man3/timeval.3bsd.gz
/usr/local/man/man3type/timeval.3type
/usr/share/man/man3/timeval.3type.gz
alx@debian:~$ man -w timeval
/usr/share/man/man3/timeval.3bsd.gz

If you want to add a page for a type that glibc doesn't provide, feel
free to do so. I even encourage you to use 3type, although that might
be inconsistent with the rest of libbsd, so you may prefer to keep 3bsd.
If you want to add a page for a type that is provided by glibc, just let
me know, and I can provide the page instead. (Although it would be rare
that you provide a page for a type that glibc provides.)

I think so.

Actually, glibc provides these macros, so I should probably write pages
for those too. Maybe I can write something and then just drop the
libbsd pages. BTW, why do you provide those macros if glibc also
provides them? Maybe they are recent additions to glibc?
alx@debian:~/src/gnu/glibc/master$ grepc TIMEVAL_TO_TIMESPEC .
./time/sys/time.h:# define TIMEVAL_TO_TIMESPEC(tv, ts) { \
(ts)->tv_sec = (tv)->tv_sec; \
(ts)->tv_nsec = (tv)->tv_usec * 1000; \
}
alx@debian:~/src/gnu/glibc/master$ grepc TIMESPEC_TO_TIMEVAL .
./time/sys/time.h:# define TIMESPEC_TO_TIMEVAL(tv, ts) { \
(tv)->tv_sec = (ts)->tv_sec; \
(tv)->tv_usec = (ts)->tv_nsec / 1000; \
}

Yeah, I remember talking to Colin Watson to have the new sections in the
right priority.

I think projects shouldn't use their own subsection. They should
instead use the same sections, in this case 3type, and use LIBRARY to
document the library needed to get the thing.
And in cases wher various projects offer the same page exact page, maybe
/etc/alternatives should decide.

Thanks!! I had to fight a bit for them. It's good to read positive
feedback. :)
