         The <code class="methodname">DbEnv::get_ext_file_threshold()</code> method
         returns the threshold value, in bytes, beyond which data items are
         stored as external files. This value can be set using
         <a class="xref" href="envset_blob_threshold.html" title="DbEnv::set_ext_file_threshold()">
        
        <span>DbEnv::set_ext_file_threshold()</span>
    </a>. A value of <code class="literal">0</code> indicates
         that external files are not in use by default in this environment,
         unless <a class="xref" href="set_blob_threshold.html" title="Db::set_ext_file_threshold()">
        
        <span>Db::set_ext_file_threshold()</span>
    </a> is called to set an external file
         threshold for a specific database.
    </p>
      <p>
         The <code class="methodname">DbEnv::get_ext_file_threshold()</code> method
         always returns <code class="literal">0</code> to indicate success.
