<h3>Berkeley DB Reference Guide: Access Methods</h3>
<p>
<h1 align=center>Record padding byte value (re_pad, DB_PAD)</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>
When storing fixed length records in the database, a pad character
may be specified by setting the <a href="../../api_c/DbInfo/info.html#DB_PAD">DB_PAD</a> flag and the
<a href="../../api_c/DbInfo/info.html#re_pad">re_pad</a> element of the DB_INFO structure. 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 this character.
<p>
If fixed-length records are specified but no pad character is specified,
a space character (i.e., 0x20 in the ASCII character set) will be used.
