XSetDeviceButtonMapping(3X11)											     XSetDeviceButtonMapping(3X11)

NAME
       XSetDeviceButtonMapping, XGetDeviceButtonMapping - query or change device button mappings

SYNOPSIS
       int XSetDeviceButtonMapping(display, device, map, nmap)
	       Display *display;
	       XDevice *device;
	       unsigned char map[];
	       int nmap;

       int XGetDeviceButtonMapping(display, device, map_return, nmap)
	       Display *display;
	       XDevice *device;
	       unsigned char map_return[];
	       int nmap;

ARGUMENTS
       Specifies  the  connection  to the X server.  Specifies the device whose button mapping is to be queried or changed.  Specifies the mapping
       list.  Returns the mapping list.  Specifies the number of items in the mapping list.

DESCRIPTION
       The XSetDeviceButtonMapping request sets the mapping of the specified device. If it succeeds, the X server generates a  DeviceMappingNotify
       event,  and  XSetDeviceButtonMapping  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 XGetDeviceButtonMapping 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,  XSetDeviceButtonMapping  returns
       MappingBusy, and the mapping is not changed.

       XSetDeviceButtonMapping can generate BadDevice, BadMatch, and BadValue errors.

       The  XGetDeviceButtonMapping  request returns the current mapping of the specified device. Buttons are numbered starting from one.  XGetDe-
       viceButtonMapping returns the number of physical buttons actually on the device. The nominal mapping for a device is map[i]=i+1.  The  nmap
       argument  specifies  the  length  of  the  array  where	the  device  mapping is returned, and only the first nmap elements are returned in
       map_return.

       XGetDeviceButtonMapping can generate BadDevice or BadMatch errors.

DIAGNOSTICS
       An invalid device was specified.  The specified device does not exist or has not been opened by this  client  via  XOpenInputDevice.   This
       error  may also occur if the specified device is the X keyboard or X pointer device.  This error may occur if an XGetDeviceButtonMapping or
       XSetDeviceButtonMapping request was made specifying a device that has no buttons.  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.
