Does Linux currently support POSIX message queues and
POSIX timers?

That is, does Linux support mq_send(), mq_receive(),
timer_settime(), etc?

I found POSIX semaphores in the glibc2 libpthread...

I'm trying to write an application portable to Linux, VxWorks,
Solaris and other sufficiently POSIX systems. POSIX message queues
and timers are required.

Thanks for letting me know,

No. It's on the agenda, but not being actively developed AFAIK.
Commonly used IPC either uses the SysV stuff(ugh) or pipes/sockets/
mmap() shm for communication and select/poll or queued real-time
signals (completion ports) or fcntl for syncronization.
