typedef uint64_t brlapi_keyCode_t
Key codes are unsigned 64 bit integers. This 64-bit space is split into 3 parts:
The second and third part are thus mandatory to tell the type of keycode and the value of the keycode, and the first part contains optional flags.
The third part is itself split into two parts: a command number and a command value. The relative sizes of these parts vary according to the key type.
For a braille command, bits 28-16 (BRLAPI_KEY_CMD_BLK_MASK) hold the braille command number, while bits 15-0 (BRLAPI_KEY_CMD_ARG_MASK) hold the command value.
The brlapi_expandKeyCode() function may be used for splitting key codes into these parts.
For a X keysym, if it is a unicode keysym (0x1uvwxyz), then the command number part is 0x1000000 and the value part is 0xuvwxyz. Else, the command part is held by bits 28-8 and the value part is held by bits 7-0. This permits to easily handle usual cases like 0x00xy (latin1), 0x01xy (latin2), XK_Backspace (0xff08, backspace), XK_Tab (0xff09, tab), ...
For instance, if key == 0x0000000020010008,
if key == 0x000000010000FF09,
in the X11 standard some keysyms are directly unicode, for instance if key == 0x0000000001001EA0,
brlapi_ignoreKeyRanges() and brlapi_acceptKeyRanges() manipulate keycode ranges. They are composed of 2 keycodes: the 'first' and the 'last' boundaries. The range expressed by these two keycodes is the set of keycodes whose lower part (bits 31-0) is between the lower part of the 'first' keycode and the 'last' keycode (inclusive), and whose high part (bits 63-32), the flags, contains at least the flags of the 'first' keycode, and at most the flags of the 'last' keycode. Setting the 'first' and 'last' keycode to the same value express only one keycode, for instance. Setting the first and last keycode to the same command code but setting no flags in the 'first' keycode and setting one flag in the 'last' keycode expresses only two keycode, with the same lower part and no flags set except possibly the flag that is set in the 'last' keycode. Setting one flag i in the 'first' keycode and setting the same flag plus another flag j in the 'last' keycode expresses that the keycodes in the range have flag i set and possibly flag j set, but no other flag.

When brlapi_enterTtyMode() or brlapi_entg$erTtyModeWithPath() is called with a driver name, brlapi_readKey() and brlapi_readKeyWithTimeout() will return driver-specific key codes. From most- to least-significant, their eight bytes are: F 0 0 0 0 0 G N. F is a byte that contains flag bits which are common for all drivers. BRLAPI_DRV_KEY_PRESS, which indicates that it's a key press (as opposed to a release) event, is the only currently defined flag. The other flag bits are always 0. G is the key's group, and N is the key's number within that group. Flag for a driver-specific keycode press (not set means a release)
