We know that boost::this_thread::sleep_for(...) can be used for putting the currently running thread into sleep. How different it is from the regular sleep() function. It seems everyplace where we use boost::this_thread::sleep_for(...) can be simply replaced by sleep() method without affecting the results. Can anyone throw some light into it.

`sleep()` isn't portable. – chris Apr 27 '15 at 03:39

C++ didn't provide a sleep function until C++11 came along, which offers std::thread::sleep_for(). So Boost provides its own for making your code platform-independent.
The C functions sleep(), usleep(), and Sleep() are platform-specific rather than part of the C++ standard library.

sleep operates only at an one second level of granularity, as were boost::this_thread::sleep_for allows for sub 1 second granularity for the sleep.
