Basically, what I'm trying to do is:
using namespace boost::posix_time; using namespace boost::this_thread;
time_duration td = milliseconds(2000); sleep(&td);
Just curious: what's the purpose of the ampersand here?

Igor, thanks for the note. My ampersand came from VS refusing to compile otherwise. But you're right, semantically it should not be there. And it's true, in win32 version this_thread::sleep() declaration is inline void sleep(TimeDuration const& rel_time) { interruptible_wait(detail::pin_to_zero(rel_time->total_milliseconds())); } TimeDuration=boost::posix_time::time_duration so rel_time->total_milliseconds() get a compiler error: type 'boost::posix_time::time_duration' does not have an overloaded member 'operator ->' D:\Projs\Libs\boost_1_46_1\boost/date_time/posix_time/posix_time_config.hpp(57) : see declaration of 'boost::posix_time::time_duration' did you intend to use '.' instead? This doesn't happen in linux version where sleep is inline void sleep(TimeDuration const& rel_time) { this_thread::sleep(get_system_time()+rel_time); } (this is the version that refused to work with boost::this_thread::sleep(&td) as in the root post) So right now, the code that works for both win32 and linux is using namespace boost::posix_time; using namespace boost::this_thread; time_duration td = milliseconds(2000); #ifdef _WIN32 sleep(&td); #else sleep(td); #endif It's probably not supposed to be like that, but this is the only way it's working for me. If anyone could come up with a more elegant solution, I'd appreciate it greatly. -- Take care, Alexey Malakhov
