Keyboard Input in OSX

Question

I was wondering if it is possible to read input data on a keyboard, on OSx from somewhere, for example GNU / Linux with / dev / input files.

The purpose of this is to make a very simple keylogger (learning goal) or if there is a function that I could call in C.

Thanks.

Since not all readers have good intentions, like yours, I will not go into details, but will point you in the right direction.

As you know, WindowServer works in two environments: Carbon (old) and Cocoa (new). These are the corresponding APIs:

• Carbon → InstallEventHandler (link is broken due to age? In any case, the reference book Study of carbon , chapter 6 - Carbon events)
• Cocoa - > addGlobalMonitorForEventsMatchingMask
