NAME

XChangeKeyboardDevice - change which device is used as the X keyboard

SYNOPSIS

 #include <X11/extensions/XInput.h>
 

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

 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.
