Comment (by Ki Hong Lee <clydelee@…>):

 new example:
 {{{
 #include <iostream>
 #include <boost/thread.hpp>

 // 1.55.0
 void boost_func()
 {
     while (true) {
         // libs/thread/src/pthread/thread.cpp : 442
         // while( thread_info->sleep_condition.do_wait_for(lk,ts)) {}

         boost::this_thread::sleep_for(boost::chrono::seconds(1));
         std::cout << "i'm boost_func !" << std::endl;
     }
 }

 // Similar to the 1.51.0 version of the sleep_for
 void posix_func()
 {
     ::timespec tm, tm1;
     while (true) {
         tm.tv_sec = 1;
         tm.tv_nsec = 0;
         ::nanosleep(&tm, &tm1);
         std::cout << "\ti'm posix_func !" << std::endl;
     }
 }

 int main()
 {
     boost::thread_group threads;
     threads.create_thread(boost_func);
     threads.create_thread(posix_func);

     threads.join_all();

     return 0;
 }
 }}}
