XQueryKeymap()															    XQueryKeymap()

Name
  XQueryKeymap - obtain a bit vector for the current state of the keyboard.

Synopsis
  XQueryKeymap(display, keys_return)
	Display *display;
	char keys_return[32];

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  keys_return
	    Returns an array of bytes that identifies which keys are pressed down.  Each bit represents one key of the keyboard.

Description
  XQueryKeymap()  returns a bit vector for the logical state of the keyboard, where each bit set to 1 indicates that the corresponding key is
  currently pressed down.  The vector is represented as 32 bytes.  Byte N (from 0) contains the bits for keys 8N to 8N+7 with the least  sig-
  nificant  bit in the byte representing key 8N.  Note that the logical state may lag the physical state if device event processing is frozen
  due to a grab.

Name
  XLookupKeysym - get the keysym corresponding to a keycode in structure.

Synopsis
  KeySym XLookupKeysym(event, index)
	XKeyEvent *event;
	int index;

Arguments
  event   Specifies the KeyPress or KeyRelease event that is to be used.

  index   Specifies  which  keysym  from the list associated with the keycode in the event to return.  These correspond to the modifier keys,
	  and the symbols ShiftMapIndex, LockMapIndex, ControlMapIndex, Mod1MapIndex, Mod2MapIndex, Mod3MapIndex, Mod4MapIndex, and  Mod5Map-
	  Index can be used.

Returns
  The keysym.

Description
  Given  a keyboard event and the index into the list of keysyms for that keycode, XLookupKeysym() returns the keysym from the list that cor-
  responds to the keycode in the event.  If no keysym is defined for the keycode of the event, XLookupKeysym() returns NoSymbol.

  Each keycode may have a list of associated keysyms, which are portable symbols representing the meanings of the key.	The  index  specifies
  which  keysym  in the list is desired, indicating the combination of modifier keys that are currently pressed.  Therefore, the program must
  interpret the state member of the XKeyEvent structure to determine the index before calling this function.  The exact mapping  of  modifier
  keys into the list of keysyms for each keycode is server-dependent beyond the fact that the first keysym corresponds to the keycode without
  modifier keys, and the second corresponds to the keycode with Shift pressed.

  XLookupKeysym() simply calls XKeycodeToKeysym(), using arguments taken from the specified event structure.

Structures
     typedef struct {
	 int type;		/* of event */
	 unsigned long serial;	/* # of last request processed by server */
	 Bool send_event;	/* true if this came from a SendEvent request */
	 Display *display;	/* display the event was read from */
	 Window window; 	/* "event" window it is reported relative to */
	 Window root;		/* root window that the event occured on */
	 Window subwindow;	/* child window */
	 Time time;		/* milliseconds */
	 int x, y;		/* pointer x, y coordinates in event window */
	 int x_root, y_root;	/* coordinates relative to root */
	 unsigned int state;	/* key or button mask */
	 unsigned int keycode;	/* detail */
	 Bool same_screen;	/* same screen flag */
     } XKeyEvent;
