XChangeKeyboardDevice(3X11)
X11R6
NAME
  XChangeKeyboardDevice - change which device is used as the X keyboard

SYNOPSIS
  Status XChangeKeyboardDevice(display, device)
	  Display *display;
	  XDevice *device;

ARGUMENTS
  display
      Specifies the connection to the X server.

  device
      Specifies the device to be used as the X keyboard.

DESCRIPTION
  The XChangeKeyboardDevice request causes the server to use the specified
  device as the X keyboard.  The device must have been previously opened by
  the requesting client via XOpenDevice or a BadDevice error will result. The
  device must support input class Keys, or a BadMatch error will result.  If
  the server implementation does not support using the requested device as
  the X keyboard, a BadDevice error will result.

  If the specified device is grabbed by another client, AlreadyGrabbed is
  returned.  If the specified device is frozen by a grab on another device,
  GrabFrozen is returned. If the request is successful, Success is returned.

  If the request succeeds, a ChangeDeviceNotify event is sent to all clients
  that have selected that event.  A MappingNotify event with request =
  MappingKeyboard is sent to all clients. The specified device becomes the X
  keyboard and the old X keyboard becomes accessible through the input
  extension protocol requests.

  XChangeKeyboardDevice can generate a BadDevice or a BadMatch error.

DIAGNOSTICS
  BadDevice
	  An invalid device was specified.  The specified device does not
	  exist, has not been opened by this client via XOpenInputDevice,  or
	  is already one of the core X device (pointer or keyboard).  This
	  error may also occur if the server implementation does not support
	  using the specified device as the X keyboard.

  BadMatch
	  This error may occur if an XChangeKeyboardDevice request was made
	  specifying a device that has no keys.
