XSetPointerMapping(3)						  XLIB FUNCTIONS					     XSetPointerMapping(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 XSet-
       PointerMapping 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.  XGetPoint-
       erMapping returns the number of physical buttons actually on the pointer.  The nominal mapping for a pointer is map[i]=i+1.  The nmap argu-
       ment 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 argu-
		 ment, the full range defined by the argument's type is accepted.  Any argument defined as a set of alternatives can generate this
		 error.
