File Information
Description

This small utility prevents, on Windows computers, the automatic sleep mode often activated by "aggressive" power policies.

Preventing computer sleep mode (a.k.a "power save") is mostly useful while doing long computations in a MATLAB script.

This utility has been inspired by the original INSOMNIA Windows utility!

The file insomnia_header.h appears to be missing from the submission.

yes, you're right. I will replace global with persistent keyword asap :)

Perhaps you want to store insomnia_prevExecState as PERSISTENT instead of GLOBAL?
