[Boost-users] Is Boost Threads missing "pthread_cancel"-like Functionality?

Hi all, i'm missing something like PThread's pthread_cancel. Is there a Way to use Boost::Threads in a similar Way. I looked in the Docu and didn't find anything similar to pthread_cancel. Is there another Functionality which kind of "implement" this Behaviour of PThreads or am i blind and don't see where it's written in the Docu? I don't want to use anything else because Boost is a very good Collection of Libraries, which are very well written.
