Name
  XUngrabKeyboard - release the keyboard from an active grab.

Synopsis
  XUngrabKeyboard(display, time)
	Display *display;
	Time time;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  time	    Specifies  the  time.   Pass either a timestamp, expressed in milliseconds, or the constant CurrentTime.  If this time is earlier
	    than the last-keyboard-grab time or later than the current server time, the keyboard will not be ungrabbed.

Description
  XUngrabKeyboard() releases any active grab on the keyboard by this client.  It executes as follows:

  o  Releases the keyboard and any queued events if this client has it actively grabbed from either XGrabKeyboard() or XGrabKey().

  o  Does not release the keyboard and any queued events if time is earlier than the last-keyboard-grab time or is later than the  current  X
     server time.

  o  Generates FocusIn and FocusOut events.

  The X server automatically performs an UngrabKeyboard if the grab_window (argument to XGrabKey() and XGrabKeyboard()) becomes unviewable.
