XSetPointerMapping(3X11)      SDK X11 R4.11MU05     XSetPointerMapping(3X11)


NAME
       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

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

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

ARGUMENTS
       display   Specifies the connection to the X server.

       map       Specifies the mapping list.

       mapreturn
                 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
       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
       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 argument, the full range defined by the
                 argument's type is accepted.  Any argument defined as a set
                 of alternatives can generate this error.
