Lock Fn keys on K400plus (for windows)

This program locks the fn key for the Logitech K380 bluetooth keyboard on Windows. Having the F1-F12 without pressing the Fn key is nice for developers.

I wanted a simple way to do the same as the Logitech Options/Options softwares WITHOUT their continuously running processes.

Running setFnKeys.exe will lock Fn key till next reboot.
Revert with setMediaKeys.exe to unlock and restore media keys.

• prerequisite : install mingw
• build setFnKeys.exe with :
  gcc main.c -o dist/setFnKeys.exe -I hidapi/include -L hidapi/x86 -lhidapi
• build setMediaKeys.exe with :
  gcc main.c -D setMediaKeys -o dist/setMediaKeys.exe -I hidapi/include -L hidapi/x86 -lhidapi
