# API
## require('winapi').getIdleTime()
Return the time the system has been idle (since last user interaction - e.g. mouse, keyboard & stuffs, see GetLastInputInfo)
This is really usefull if you want to create a screensaver/like in nodejs / node-webkit.
```
var winapi = require('winapi');
console.log("System is idle since %s", winapi.getIdleTime() );
```
## require('winapi').CreateJobGroup()
Create a [job group](https://docs.microsoft.com/fr-fr/windows/desktop/ProcThread/job-objects) with current process and all future child_process. Use this to kill zombies. Like Rick.
```
var winapi = require('winapi');
winapi.CreateJobGroup();
//you can now spawn subprocess and they'll be killed once you died, windows will clean everything up
```
* (checkout my [dispatcher](https://github.com/131/dispatcher) project for inspiration)
* Available for node 8, nw 26 and nw 14. (i did not re-compile other platform binaries, do it by yourself...)
## require('winapi').GetLastInputInfo()
Use this native binding to get system last input time ([see MSDN](https://msdn.microsoft.com/en-us/library/windows/desktop/ms646302%28v=vs.85%29.aspx) )
```
var winapi = require('winapi');
console.log("Last input time is %s", winapi.GetLastInputInfo() );
setTimeout(function(){
//do not move, it wont change !
console.log("Last input time is %s", winapi.GetLastInputInfo() );
}, 1000);
```
## require('winapi').GetChildrenProcess([parentProcessId])
List all children process (of specified parent PID, default to current process)
## require('winapi').GetParentProcess([childProcessId])
Get a process parent PID (of specified process PID, default to current process)
## require('winapi').GetTickCount()
Retrieves the number of milliseconds that have elapsed since the system was started (uptime). ([see MSDN](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724408%28v=vs.85%29.aspx) )
### require('winapi').GetDisplaysList(console.log)
List all connected screens
