Problem Description

OS : Windows

I would like a way to prevent windows sign out/shutdown until i finish/stop my running tasks.

Proposed Solution

Add the following functions

app.preventShutDown(reason)

When it is called the following should happen:
[ ] call the ShutdownBlockReasonCreate API to prevent the shutdown.
[ ] all windows that receive the WM_QUERYENDSESSION event should return false

app.releaseShutDown()

This function should call ShutdownBlockReasonDestroy witch will allow the sign out/shutdown of windows.

Alternatives Considered

For now the method i use to achieve this result is using the node-ffi addon. But that is a complicated and not very efficient method.
