<p>
The <code class="methodname">DB_CHANNEL->close()</code> method
closes the DB_CHANNEL handle, freeing any resources
allocated to the handle. All DB_CHANNEL 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.

<p>
After <code class="methodname">DB_CHANNEL->close()</code> has been
called, regardless of its return, the DB_CHANNEL handle may
not be accessed again.
</p>
<p>
The <code class="methodname">DB_CHANNEL->close()</code> <span>
