+ <p>Orders the event manager <c>EventMgrRef</c> to exit with

+ terminate. Before terminating, the gen_event will call
+ <seealso marker="#Module:terminate/2">Module:terminate(stop,...)</seealso>
+ for each installed event handler.</p>
+ <p>The function returns <c>ok</c> if the event manager terminates
+ with the expected reason. Any other reason than <c>normal</c>,
+ <c>shutdown</c>, or <c>{shutdown,Term}</c> will cause an
+ error report to be issued using
+ <seealso marker="kernel:error_logger#format/2">error_logger:format/2</seealso>.
+ The default <c>Reason</c> is <c>normal</c>.</p>
+ <p><c>Timeout</c> is an integer greater than zero which
+ specifies how many milliseconds to wait for the event manager to
+ terminate, or the atom <c>infinity</c> to wait
+ indefinitely. The default value is <c>infinity</c>. If the
+ event manager has not terminated within the specified time, a
+ <c>timeout</c> exception is raised.</p>
