How Can I Sleep for a Specific Number of Milliseconds in C ?

Sleeping in Milliseconds in C

While the POSIX sleep(x) function allows for sleeping for a specified number of seconds, there may be scenarios where finer-grained control over the sleep duration is required, specifically in milliseconds. In C , the standard library provides a solution to this need.

In C 11, the and headers introduce new facilities for working with time and concurrency, including a method for precise sleeping: std::this_thread::sleep_for(). This function takes an argument of type std::chrono::milliseconds, which represents a duration of milliseconds.

For example, to make the program sleep for x milliseconds, you can use the following code:

#include <chrono>
#include <thread>

std::this_thread::sleep_for(std::chrono::milliseconds(x));

This sleep_for() function is clear, readable, and eliminates the need for guessing the units of the sleep() function. It provides precise control over the duration of the sleep, allowing for finer-grained control in your C programs.
