It would be nice if it was possible to pass a time_duration object to sleep() directly:
boost::thread::sleep(boost::posix_time::seconds(5)); boost::thread::sleep is only provided for backwards compatibility. boost::this_thread::sleep has the absolute time/duration overloads you desire: boost::this_thread::sleep(boost::posix_time::seconds(5));
The current proposal n2497 contains two overloadings http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2497.html void boost::this_thread::sleep(const system_time& abs_t); template <class Duration> void boost::this_thread::sleep(const Duration& rel_t);
Boost.Thread contains only the template <class Duration> void boost::this_thread::sleep(const Duration& rel_t);
Could you add the other?
N2497 was overridden by N2661:

This is all put together in the latest working draft:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2798.pdf
namespace std { namespace this_thread {
template <class Clock, class Duration> void sleep_until(const chrono::time_point<Clock, Duration>& abs_time); template <class Rep, class Period> void sleep_for(const chrono::duration<Rep, Period>& rel_time);
} }
Yes, I know that, see my preceding post.
Ah, sorry 'bout that. You caught me skimming. :-)
But we don't have yet chrono in boost.
I'm probably skimming too fast again, but just in case you were too, Beman has this ready to go: See http://svn.boost.org/svn/boost/sandbox/chrono
Waiting for that maybe Anthony can add this
template <class AbsoluteTime> void boost::this_thread::sleep_until(Time& abs_t); template <class Duration> void boost::this_thread::sleep_for(const Duration& rel_t);
I'll leave it Anthony (of course), but these signatures look overly generic to me (anything will bind to them). -Howard
