[Boost-users] Thread prioritization on OSX

Hello all,

according to this:

http://www.boost.org/doc/libs/1_57_0/doc/html/thread/thread_management.html
#thread.thread_management.tutorial.attributes

I tried to change the thread priority to SCHED_RR on OS X via:

boost::thread::attributes attrs;
pthread_attr_setschedpolicy(attrs.get_native_handle(), SCHED_RR);
    sendThread = boost::thread(attrs,&sender::sendItThreadFunction,this);

In that context I noticed that get_native_handle is not known so I used
attr.native_handle(), which compiled ok but finally threw an error here:

/boost/boost/bind/bind.hpp:313:9: Type 'boost::thread_attributes' does not
provide a call operator

I am still using boost 1.45 and wonder if this is the actual problem or if
something else is wrong.

Any help appreciated,
thanks

Alex
