Reading thread state

[Peter Skvarka <ps%softinengines.com@localhost>]

Hello,

in main application thread I have valid pthread_t of another thread.
Does NetBSD provide any pthread...() function or another interface for 
reading thread state ? (RUNNING, DEAD, ZOMBIE)

I found way only with reading of internal __pthread_st.pt_state but I'd 
like to avoid this way.
