NAME

       keyboard_getstate  -  get  a  pointer  to  a  buffer  holding the state of all keys in raw
       keyboard mode

SYNOPSIS

       #include <vgakeyboard.h>

       char *keyboard_getstate(void);

DESCRIPTION

       When in raw keyboard mode this routine returns a pointer buffer to a static buffer. If the
       value  in  buffer[scancode] is KEY_PRESSED or KEY_NOTPRESSED the key with that scancode is
       pressed or not. Actually KEY_PRESSED is 1 and  KEY_NOTPRESSED  is  0,  s.t.  you  can  use
       constructs like:

       if(buffer[SCANCODE_ENTER]) {
            /* do something */
       }

       This  is  more efficient than calling keyboard_keypressed(3) if you want to check for many
       different keys.

       Please note that keyboard events  will  only  be  processed  when  you  occasionally  call
       keyboard_update(3) or keyboard_waitforupdate(3).

       keyboard_translatekeys(3) allows certain remap operations which make certain keys (digits,
       enter) which might have several physical keys show up under the same scancodes.

       Here are the supported scancodes. The names of the #defines originate from the US keyboard
       layout,  for  other countries, they'll refer to the key in the same physical location, but
       the keycap will have a different inscription. For the list below, add SCANCODE_  in  front
       of  the  names  to get the right name for your C source. That means, if it lists BACKSLASH
       below, you shall use SCANCODE_BACKSLASH as symbol in your  program.  In  addition  to  the
       names  below  we  also  have SCANCODE_0 - SCANCODE_9, SCANCODE_KEYPAD0 - SCANCODE_KEYPAD9,
       SCANCODE_A - SCANCODE_Z, and SCANCODE_F1 - SCANCODE_F12.

       The other key names are ESCAPE, MINUS, EQUAL, BACKSPACE, TAB, BRACKET_LEFT, BRACKET_RIGHT,
       ENTER,  LEFTCONTROL,  SEMICOLON,  APOSTROPHE,  GRAVE, LEFTSHIFT, BACKSLASH, COMMA, PERIOD,
       SLASH,  RIGHTSHIFT,  KEYPADMULTIPLY,  LEFTALT,  SPACE,  CAPSLOCK,   NUMLOCK,   SCROLLLOCK,
       CURSORUPLEFT,  CURSORUP,  CURSORUPRIGHT, KEYPADMINUS, CURSORLEFT, CURSORRIGHT, KEYPADPLUS,
       CURSORDOWNLEFT,   CURSORDOWN,   CURSORDOWNRIGHT,    KEYPADPERIOD,    LESS,    KEYPADENTER,
       RIGHTCONTROL,  CONTROL,  KEYPADDIVIDE,  PRINTSCREEN,  RIGHTALT,  BREAK, BREAK_ALTERNATIVE,
       HOME, CURSORBLOCKUP,  PAGEUP,  CURSORBLOCKLEFT,  CURSORBLOCKRIGHT,  END,  CURSORBLOCKDOWN,
       PAGEDOWN, INSERT, and REMOVE.
