XSetPointerMapping(3X11)             BSD              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
     XSetPointerMapping returns MappingSuccess.  Elements of the list are
     indexed starting from one.  The length of the list must be the same as
     XGetPointerMapping would return, or a BadValue error results.  The index
     is a core button number, and the element of the list defines the
     effective number.  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.  Elements of the list are indexed starting from one.
     XGetPointerMapping returns the number of physical buttons actually on the
     pointer.  The nominal mapping for a pointer is the identity mapping:
     map[i]=i.  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.
