Name
  XSetPointerMapping - set the pointer button mapping.

Synopsis
  int XSetPointerMapping(display, map, nmap)
	Display *display;
	unsigned char map[];
	int nmap;

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

  map	    Specifies the mapping list.

  nmap	    Specifies the number of items in the mapping list.

Returns
  MappingSuccess on success; MappingBusy on failure.

Description
  XSetPointerMapping()	sets  the  mapping  of the pointer buttons.  Elements of the map list are indexed starting from 1.  The length of the
  list nmap must be the same as XGetPointerMapping() returns (you must call that first).  The index is a physical button number, and the ele-
  ment of the list defines the effective button number.  In other words, if map[2] is set to 1, when the second physical button is pressed, a
  ButtonPress event will be generated if Button1Mask was selected but not if Button2Mask was selected.	The button member in the  event  will
  read Button1.

  No  two  elements  can  have the same non-zero value (else a BadValue error).  A value of zero for an element of map disables a button, and
  values for elements are not restricted in value by the number of physical buttons.  If any of the buttons to be altered  are	currently  in
  the down state, the returned value is MappingBusy and the mapping is not changed.

  This	function returns either MappingSuccess or MappingBusy.	XSetPointerMapping() generates a MappingNotify event when it returns Mapping-
  Success.

Errors
  BadValue  Two elements of map[] have same non-zero value.
	    nmap not equal to XGetPointerMapping() return value.
