XDisplayKeycodes()														XDisplayKeycodes()

Name
  XDisplayKeycodes - obtain the range of legal keycodes for a server.

Synopsis
  XDisplayKeycodes(display, min_keycodes_return, max_keycodes_return)
	Display *display;
	int *min_keycodes_return, *max_keycodes_return;

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

  min_keycodes_return
	      Returns the minimum keycode.

  max_keycodes_return
	      Returns the maximum keycode.

Description
  XDisplayKeycodes()		    returns		  the		    min_keycodes_return 	      and		max_keycodes_
  return supported by the specified server.  The minimum keycode returned is never less than 8, and the maximum  keycode  returned  is	never
  greater than 255.  Not all keycodes in this range are required to have corresponding keys.

  For more information, see Volume One, Chapter 9, The Keyboard and Pointer.

XChangeKeyboardMapping()												  XChangeKeyboardMapping()

Name
  XChangeKeyboardMapping - change the keyboard mapping.

Synopsis
  XChangeKeyboardMapping(display, first_keycode,
  keysyms_per_keycode, keysyms, num_codes)
	Display *display;
	int first_keycode;
	int keysyms_per_keycode;
	KeySym *keysyms;
	int num_keycodes;

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

  first_keycode
	   Specifies the first keycode that is to be changed.

  keysyms_per_keycode
	   Specifies the number of keysyms that the caller is supplying for each keycode.

  keysyms  Specifies a pointer to the list of keysyms.

  num_keycodes
	   Specifies the number of keycodes that are to be changed.

Description
  Starting  with  first_keycode, XChangeKeyboardMapping() defines the keysyms for the specified number of keycodes.  The symbols for keycodes
  outside   this   range   remain   unchanged.	  The	number	 of    elements    in	 the	keysyms    list    must    be	 keysyms_per_
  keycode * num_keycodes (else a BadValue error).  The specified first_keycode must be greater than or equal to min_keycode returned by XDis-
  playKeycodes() (see Appendix C, Macros) or a BadValue error results.	In addition, the following expression must be less than or  equal  to
  max_keycode as returned by XDisplayKeycodes(), or a BadValue error results:

     first_keycode + num_keycodes  - 1

  The keysym number N (counting from 0) for keycode K has the following index in the keysyms array (counting from 0):

     (K - first_keycode) * keysyms_per_keycode + N

  The specified keysyms_per_keycode can be chosen arbitrarily by the client to be large enough to hold all desired symbols.  A special keysym
  value of NoSymbol should be used to fill in unused elements for individual keycodes.	It is legal for NoSymbol  to  appear  in  nontrailing
  positions of the effective list for a keycode.

  XChangeKeyboardMapping() generates a MappingNotify event, sent to this and all other clients, since the keycode to keysym mapping is global
  to all clients.

Errors
  BadAlloc

  BadValue  first.keycode less than display->min_keycode.
	    display->max_keycode exceeded (see above).
