ManualMap | A Simple demonstration of manual dll injector

so here's what I wanna do.

I have a driver that I haven't made and I manual map it. Say the function is ManualMap(); as an example.

That function gets called everytime I run my program. It's basically in main();

Now what I want to do is to make that function only be called once every session. So if PC was restarted, that function will be called, if u run the program again during the same pc session, it won't run the function. Now if you restart PC, the function will be called when you run the program.

I hope u got my idea and what I want to do :D
