keymap.library — Keyboard Mapping

Overview

keymap.library translates raw keycodes from keyboard.device into character codes using the active keymap. Each keymap defines the mapping from physical keys to characters, including dead keys and string sequences.

Key Functions

/* Map a raw keycode + qualifiers to ASCII: */
LONG actual = MapRawKey(&inputEvent, buffer, bufsize, NULL);
/* Returns number of characters, -1 if buffer too small */

/* Map ANSI code back to raw key: */
WORD MapANSI(STRPTR string, WORD count,
             STRPTR buffer, WORD length,
             struct KeyMap *keyMap);

struct KeyMap

/* devices/keymap.h — NDK39 */
struct KeyMap {
    UBYTE *km_LoKeyMapTypes;    /* type array for keys 0x00–0x3F */
    ULONG *km_LoKeyMap;         /* mapping array for keys 0x00–0x3F */
    UBYTE *km_LoCapsable;       /* caps-lock bitmap */
    UBYTE *km_LoRepeatable;     /* auto-repeat bitmap */
    UBYTE *km_HiKeyMapTypes;    /* type array for keys 0x40–0x77 */
    ULONG *km_HiKeyMap;
    UBYTE *km_HiCapsable;
    UBYTE *km_HiRepeatable;
};
