How to access the IR (Infrared receiver) with Cocoa?

I need to access the raw data of the IR with cocoa, but not only the received from the Apple Remote. I saw this https://github.com/martinkahr/apple_remote_control but It's only for the Apple Remote.

Solution

Just from a quick browse over the source you linked to, it appears that what you're looking for is the I/O Kit. Specifically the HID (human input device aspects of it).

This seems to be the bridging layer between Mac OS applications the the hardware itself.
