Limit to single instance

[4o66]

Since KSP-MA saves its config at close, if you accidentally have multiple copies open, your config will be set to the last closed copy.

Need to limit to a single running instance.

I can realize this for windows easily but i have no idea of how to implment it for the mono verion.

The traditional move is to drop a file on disk with a unique random number.

1. On app launch, check to see if this file exists. If exists, warn the user that the app is either still running, or didn't quit cleanly. (You can ask user if they want to proceed anyway).
2. If file is missing, then create with unique number.
3. On quit, delete this file (if it contains your unique number).

If you want to get fancy, the number you write can be your pid (process-id). Then you can query the system to see if mod-admin is still running with that process-id. If it is still running, you can offer the user the option of force-killing the previous instance (kill -9 <pid>) OR you can bring that process into the foreground.

This level of fancy is called the pidfile technique, while the simpler version is a lock file. Tutorial
