Emulate keyboard event arrow keys in C

Question

Short: help emulate keyboard events (arrow keys, enter) in C code under linux.

Long: I am working at interfacing iPod clickwheel with Raspberry Pi. At the moment i can printf to terminal something like "button 1 pressed". But i need system-wide event, just like a keypress from real keyboard. My other code is on C so i cant implement Python.

You can maybe use SDL2, it works with Raspberry Pi and Linux and you can manage inputs events such as keyboard, mouse, pads etc.

You really should use third-party libraries. There's definitely no platform-independent way to do it in ANSI C. You can try using conio.h with its kbhit() function , the library can be downloaded from conio.

Or you can read the up /down /right /left keys from the terminal like
