Requires
c++11
or newer.
Intent
Block the execution of a thread for a given amount of time.
Description
On line 7, we create a std::chrono::milliseconds
object representing the number of milliseconds to sleep (other
duration units may also be used). On line 8, the call to
std::this_thread::sleep_for will block
the execution of the current thread for at least the given
duration.
On line 10, we demonstrate the use of C++14’s duration literal
suffixes
by representing a duration with the seconds suffix, s. The
using directive on line 4 is required in order to use these suffixes.
