<h1>Description</h1>
<p>Set the prefix string that appears before error messages issued by Berkeley DB.
<p>The <a href="../api_cxx/db_set_errpfx.html">Db::set_errpfx</a> and DbEnv::set_errpfx methods do not copy
the memory to which the <b>errpfx</b> argument refers; rather, they
maintain a reference to it. Although this allows applications to modify
the error message prefix at any time (without repeatedly calling the
interfaces), it means the memory must be maintained until the handle is
closed.
<p>The DbEnv::set_errpfx interface may be called at any time during the life of
the application.
