Not a problem. It looks as if it goes into the # elif defined(BOOST_HAS_NANOSLEEP) section.

Sorry, I forgot all about answering your original post. If you look at the thread::sleep() method, it looks like the following; can you tell me which path it's taking (there are several options for pthreads) when you have the problem? void thread::sleep(const xtime& xt) { for (int foo=0; foo < 5; ++foo) { #if defined(BOOST_HAS_WINTHREADS) int milliseconds; to_duration(xt, milliseconds); Sleep(milliseconds); #elif defined(BOOST_HAS_PTHREADS) # if defined(BOOST_HAS_PTHREAD_DELAY_NP) timespec ts; to_timespec_duration(xt, ts); int res = 0; res = pthread_delay_np(&ts); assert(res == 0); # elif defined(BOOST_HAS_NANOSLEEP) timespec ts; to_timespec_duration(xt, ts); // nanosleep takes a timespec that is an offset, not // an absolute time. nanosleep(&ts, 0); # else mutex mx; mutex::scoped_lock lock(mx); condition cond; cond.timed_wait(lock, xt); # endif #elif defined(BOOST_HAS_MPTASKS) int microseconds; to_microduration(xt, microseconds); Duration lMicroseconds(kDurationMicrosecond * microseconds); AbsoluteTime sWakeTime(DurationToAbsolute(lMicroseconds)); threads::mac::detail::safe_delay_until(&sWakeTime); #endif xtime cur; xtime_get(&cur, TIME_UTC); if (xtime_cmp(xt, cur) <= 0) return; } } Mike _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
