xgetdevicebuttonmapping

XSetDeviceButtonMapping(3X11)					    X FUNCTIONS 				     XSetDeviceButtonMapping(3X11)

NAME

       XSetDeviceButtonMapping, XGetDeviceButtonMapping - query or change device button mappings

SYNTAX

       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

       display	   Specifies the connection to the X server.

       device	   Specifies the device whose button mapping is to be queried or changed.

       map	   Specifies the mapping list.

       map_return  Returns the mapping list.

       nmap	   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

       BadDevice   An  invalid	device was specified.  The specified device does not exist or has not been opened by this client via XOpenInputDe-
		   vice.  This error may also occur if the specified device is the X keyboard or X pointer device.

       BadMatch    This error may occur if an XGetDeviceButtonMapping or XSetDeviceButtonMapping request was made specifying a device that has	no
		   buttons.

       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  gener-
		   ate this error.
