NAME
     XISetFocus, XIGetFocus - set or get the device's focus.

SYNOPSIS
     cc [ flag... ] file... -lXi [ library... ]

     #include 

     Status XISetFocus( Display *display,
                        int deviceid,
                        Window focus,
                        Time time);

     Status XIGetFocus( Display *display,
                        Window *focus_return);

     display
            Specifies the connection to the X server.

     deviceid
            Specifies the device whose focus is to be queried or
            changed.

     focus
            The new focus window.

     focus_return
            Returns the current focus window.

     time
            A valid timestamp or CurrentTime.

DESCRIPTION
         XISetFocus changes the focus of the specified device ans its
         last-focus-change time. It has no effect if the specified time
         is earlier than the current last-focus-change time or is later
         than the current X server time. Otherwise, the
         last-focus-change time is set to the specified time.
         CurrentTime is replaced by the current X server time).
         XISetFocus causes the X server to generate core, XI and XI2
         focus events.

         If the focus window is None all keyboard events by this device
         are discarded until a new focus window is set. Otherwise, if
         focus is a window, it becomes the device's focus window. If a
         generated device event would normally be reported to this
         window or one of its inferiors, the event is reported as usual.
         Otherwise, the event is reported relative to the focus window.

         The specified focus window must be viewable at the time
         XISetFocus is called, or a BadMatch error results. If the focus
         window later becomes not viewable, the focus reverts to the

         parent (or the closest viewable ancestor. When the focus
         reverts, the X server generates core, XI and XI2 focus events
         but the last-focus-change time is not affected.

         Attempting to set the focus on a master pointer device or an
         attached slave device will result in a BadDevice error.

         XISetFocus can generate BadDevice, BadMatch, BadValue, and
         BadWindow errors.

DIAGNOSTICS
         BadValue
                A value is outside of the permitted range.

         BadDevice
                An invalid device was specified. The device does not
                exist or is not a appropriate for the type of change.

         BadMatch
                The window is not viewable.

         BadWindow
                A value for a Window argument does not name a defined
                Window.
