<h3>Berkeley DB Reference Guide: Access Methods</h3>
<p>
<h1 align=center>Record length (re_len, DB_FIXEDLEN)</h1>
<p>
The Recno access method can be used to store both variable and
fixed-length data items. By default, the data items are expected
to be variable length. If the <a href="../../api_c/DbInfo/info.html#DB_FIXEDLEN">DB_FIXEDLEN</a> flag is set
in the DB_INFO structure during the <a href="../../api_c/Db/open.html">db_open</a> call
to open the database, the data items are expected to be fixed-length.
<p>
Any record read from the <a href="re_source.html">backing source file</a> or
otherwise stored in the database that is shorter than the expected
length will automatically be padded with the <a href="../../api_c/DbInfo/info.html#re_pad">re_pad</a> character.
