sleep


sleep
=====

Add [sleep()][1], msleep() and [usleep()][2] to Node.js, via a C++ binding.

This is mainly useful for debugging.

Note that because this is a C++ module, it will need to be built on the system you are going to use it on.

These calls will block execution of all JavaScript by halting Node.js' event loop!
==================================================================================

Alternative
-----------

When using nodejs 9.3 or higher it's better to use Atomics.wait which doesn't require compiling this C++
module.
The sleep and msleep functions can be implemented like this:
``js
function msleep(n) {
Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), 0, 0, n);
}
function sleep(n) {
msleep(n*1000);
}
`
If you require usleep this module is still required.

Usage
-----

var sleep = require('sleep');

* sleep.sleep(n): sleep for n seconds
* sleep.msleep(n): sleep for n miliseconds
* sleep.usleep(n): sleep for n` microseconds (1 second is 1000000 microseconds)
