Setting thread priority in Linux with Boost

The Boost Libraries don't seem to have a device for setting a thread's priority. Would this be the best code to use on Linux or is there a better method?

boost::thread myThread( MyFunction() );

struct sched_param param;
param.sched_priority = 90;
pthread_attr_setschedparam( myThread.native_handle(), SCHED_RR, &param);

I don't have alot of Linux programming experience.
