Putting a program to sleep for specific amounts of time

A nice and simple possibility to control threads came with C++11. It introduced the this_thread namespace, which includes functions that affect only the caller thread. It contains two different functions that allow putting a thread to sleep for a certain amount of time, so we do not need to use any external or operating system-dependent libraries for such tasks any longer.

In this recipe, we concentrate on how to suspend threads for a certain amount of time, or how to put them to sleep.

How to do it...

We will write a short program that just puts the main thread to sleep for certain amounts of time:

1. Let's first include all the needed headers and declare that we...
