Igor,

As far as I know, boost::thread does not provide any mechanism for
this.  However, you can use OS-specific system calls to get this
information.  For example, on my Unix system I use pthread_self() to
get a thread ID.

boost::threads are very portable and so implement only the
functionality that can be provided identically on all platforms.
That's their greatest strength and their greatest weakness.

Good luck!
