Hi friends,
I seems that i have buggy implementation of pthread_timedjoin_np.
Although linux does not documented this function yet ( see
http://www.kernel.org/doc/man-pages/missing_pages.html ), I suspect that
on my installation
this function does not work properly because it returns sometimes 0,
sometimes 110 and does not set errno to ETIMEOUT.
After some googling I still do not know how to get thread status.
As an idea i thought about using the futex() to check memory pointed my
thread handle, but
I am almost sure this solution (if pthread handle indeed references
memory) is dirty, ...
I saw on this list people with experience in thread programming and I
am hope for you help.
Cheers,

Hi Lev,
why do you want to use this non-posix API in the first place?
APIs ending with '_np' are not part of the pthreads spec - and thus are
not portable and should be avoided.
why can't you use the standard pthread_join API?
and if you need a work-around you can use some portable mechanism, e.g.
synchronizing using a condition variable, having the inner thread signal
it just before terminating, and the outer thread waiting on it just
before calling pthread_join?
