XSetPointerMapping(3X11)       XLIB FUNCTIONS	     XSetPointerMapping(3X11)



NAME
  XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

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

  int XGetPointerMapping(display, map_return, nmap)
	Display *display;
	unsigned char map_return[];
	int nmap;

ARGUMENTS

  display   Specifies the connection to the X server.

  map	    Specifies the mapping list.

  map_return
	    Returns the mapping list.

  nmap	    Specifies the number of items in the mapping list.

DESCRIPTION
  The XSetPointerMapping function sets the mapping of the pointer.  If it
  succeeds, the X server generates a MappingNotify event, and XSetPointerMap-
  ping returns MappingSuccess.	Element map[i] defines the logical button
  number for the physical button i+1.  The length of the list must be the
  same as XGetPointerMapping would return, or a BadValue error results.	 A
  zero element disables a button, and elements are not restricted in value by
  the number of physical buttons.  However, no two elements can have the same
  nonzero value, or a BadValue error results.  If any of the buttons to be
  altered are logically in the down state, XSetPointerMapping returns Map-
  pingBusy, and the mapping is not changed.

  XSetPointerMapping can generate a BadValue error.

  The XGetPointerMapping function returns the current mapping of the pointer.
  Pointer buttons are numbered starting from one.  XGetPointerMapping returns
  the number of physical buttons actually on the pointer.  The nominal map-
  ping for a pointer is map[i]=i+1.  The nmap argument specifies the length
  of the array where the pointer mapping is returned, and only the first nmap
  elements are returned in map_return.

DIAGNOSTICS

  BadValue  Some numeric value falls outside the range of values accepted by
	    the request.  Unless a specific range is specified for an argu-
	    ment, the full range defined by the argument's type is accepted.
	    Any argument defined as a set of alternatives can generate this
	    error.
