/* Keysym structure
   - The scancode is hardware dependent, and should not be used by general
     applications.  If no hardware scancode is available, it will be 0.

   - The 'unicode' translated character is only available when character
     translation is enabled by the SDL_EnableUNICODE() API.  If non-zero,
     this is a UNICODE character corresponding to the keypress.  If the
     high 9 bits of the character are 0, then this maps to the equivalent
     ASCII character:
      char ch;
      if ( (keysym.unicode & 0xFF80) == 0 ) {
            ch = keysym.unicode & 0x7F;
      } else {
            An international character..
struct SDL_keysym {
      Uint8 scancode;               /* hardware specific scancode */
      SDLKey sym;             /* SDL virtual keysym */
      SDLMod mod;             /* current key modifiers */
      Uint16 unicode;               /* translated character */

/* This is the mask which refers to all hotkey bindings */
const uint SDL_ALL_HOTKEYS          = 0xFFFFFFFF;

/* Function prototypes */
 * Enable/Disable UNICODE translation of keyboard input.
 * This translation has some overhead, so translation defaults off.
 * If 'enable' is 1, translation is enabled.
 * If 'enable' is 0, translation is disabled.
 * If 'enable' is -1, the translation state is not changed.
 * It returns the previous state of keyboard translation.
int SDL_EnableUNICODE(int enable);

 * Enable/Disable keyboard repeat.  Keyboard repeat defaults to off.
 * 'delay' is the initial delay in ms between the time when a key is
 * pressed, and keyboard repeat begins.
 * 'interval' is the time in ms between keyboard repeat events.
const uint SDL_DEFAULT_REPEAT_DELAY       = 500;
 * If 'delay' is set to 0, keyboard repeat is disabled.
int SDL_EnableKeyRepeat(int delay, int interval);

 * Get a snapshot of the current state of the keyboard.
 * Returns an array of keystates, indexed by the SDLK_* syms.
 * Used:
 *    Uint8 *keystate = SDL_GetKeyState(NULL);
 *    if ( keystate[SDLK_RETURN] ) ... <RETURN> is pressed.
Uint8 * SDL_GetKeyState(int *numkeys);

 * Get the current key modifier state
SDLMod SDL_GetModState();

 * Set the current key modifier state
 * This does not change the keyboard state, only the key modifier flags.
void SDL_SetModState(SDLMod modstate);

 * Get the name of an SDL virtual keysym
char * SDL_GetKeyName(SDLKey key);
