The <code class="methodname">DbChannel::close()</code> method

closes the DbChannel handle, freeing any resources

allocated to the handle. All DbChannel handles must be
|

closed before the encompassing environment handle is closed.

Also, all on-going messaging operations on the channel should be

allowed to complete before attempting to close the channel handle.
