XGetPointerMapping(3)


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
   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.
