NAME

       keyboard_keypressed  -  check  if a key is pressed when in raw keyboard
       mode

SYNOPSIS

       #include <vgakeyboard.h>

       int keyboard_keypressed(int scancode);

DESCRIPTION

       When in raw keyboard mode this routine checks if the key with  scancode
       is  pressed  and  returns  KEY_PRESSED  or  KEY_NOTPRESSED accordingly.
       Actually KEY_PRESSED is 1 and KEY_NOTPRESSED is 0,  s.t.  you  can  use
       constructs like:

       if(keyboard_keypressed(SCANCODE_ENTER)) {
            /* do something */
       }

       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.
