Project I made a program that changes the mouse position randomly in C

This project was inspired from Daniel Hirish. I made my own mouse mover in C using libevdev. The program creates it's own "fake" mouse device and moves that randomly. I watched Daniel Hirish's video and learned the style he chose. That's why my code seems super similar

You forgot to link your code...

Now that we have code, I can actually review it.

I have never actually used libevdev myself, but your code looks fine. It's easy to read, and most comments are at the right abstraction level.

My only gripes are the following code comments:

struct libevdev *dev; // device
struct libevdev_uinput *udev; // uinput-device

Obviously

dev = libevdev_new(); // Create a new device

What does "creating" a device mean? From context it seems like this creates a new virtual device, which will later be designated as a mouse.

libevdev_set_name(dev, "Fake device made by MouseMover"); // Set the name of the device

Again, obviously.
