NAME

       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

SYNTAX

       int XSetPointerMapping(Display *display, _Xconst 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.
