No, brlapi_expandedKeyCode can only be used on non-device-specific
key codes.

It's all in the manual pages: man BRLAPI_KEY_FLG_MOD1 etc., and in
brlapi_keycodes.h

But again, that's only for non-device-specific key codes.


For device-specific key codes, only the BRLAPI_RAWKEY_PRESS flag is
defined, that will exactly tell you whether it's a key press or key
release (we are currently discussing whether to rename it actually).
