The <code class="methodname">Db::get_re_len()</code> method returns the length of the records held
in a Queue access method database. This value can be set using the
<a class="xref" href="dbset_re_len.html" title="Db::set_re_len()">Db::set_re_len()</a>
method.

<p>
The <code class="methodname">Db::get_re_len()</code> method may be
called only after the database has been opened.

<p>
The <code class="methodname">Db::get_re_len()</code> <span>

exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
