If BOOST_THREAD_DEFINES_THREAD_ATTRIBUTES_NATIVE_HANDLE is defined,
boost::thread has a native_handle_type and a native_handle() function.

You can use those (pthread_t, HANDLE, whatnot) with your native platform
functionality of choice to adjust thread priority, if such a concept
exists.

A reason it doesn't exist in Boost is because not all platforms has an
uniform "priority" system with the same kind of absolute/relative
priorities and tiers.
