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



NAME
       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

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

       int XGetPointerMapping(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 XSet-
       PointerMapping 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 Bad-
       Value error results.  A zero element disables a button, and elements
       are not restricted in value by the number of physical buttons.  How-
       ever, 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 MappingBusy, and the map-
       ping 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.  XGetPoint-
       erMapping returns the number of physical buttons actually on the
       pointer.	 The nominal mapping 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 speci-
		 fied for an argument, the full range defined by the argu-
		 ment’s type is accepted.  Any argument defined as a set of
		 alternatives can generate this error.
