Your program is running in the background? If it is a daemon, to capture key, is likely to be more thorough understanding of the Linux kernel "input" input subsystem, or/dev/input/event handling,
Now you output the wrong data should be coding problem, need to input accordingly,

For example, in a development version (no screen, through SSH terminal operation) plug in a usb keyboard), I need real-time monitoring program what characters, tapping the keyboard I know/dev/input/event * can monitor keyboard events, related code can also find on the net, I under a demo, knock down the Q button, printed is

 type: 4 code: the value of 16:0 

according to the input. H 16 is on behalf of the Q key can know, but I need the string, not plastic, have a way to put these plastic value converted to the corresponding string?
