       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings


       int XSetPointerMapping(Display *display, unsigned char map[], int

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


       display   Specifies the connection to the X server.

       map       Specifies the mapping list.

                 Returns the mapping list.

       nmap      Specifies the number of items in the mapping list.


       The XSetPointerMapping function sets the mapping of the pointer.  If it
       succeeds, the X server generates a MappingNotify event, and
       XSetPointerMapping 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 MappingBusy, 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 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


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