<a class="xref" href="envset_errpfx.html" title="DB_ENV->set_errpfx()">DB_ENV->set_errpfx()</a>

methods do not copy the memory to which the <span class="bold"><strong>errpfx</strong></span> parameter 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.

For <a class="link" href="db.html" title="Chapter 2. The DB Handle">DB</a> handles opened
|

inside of Berkeley DB environments, calling the <code class="methodname">DB->set_errpfx()</code>
|

method affects the entire environment and is equivalent to calling the
|
||
<a class="xref" href="envset_errpfx.html" title="DB_ENV->set_errpfx()">DB_ENV->set_errpfx()</a>
|
||
method.
|

</p>
|

<p>
|
||
The <code class="methodname">DB->set_errpfx()</code> method configures operations performed using the
|

specified <a class="link" href="db.html" title="Chapter 2. The DB Handle">DB</a> handle, not
|
||
all operations performed on the underlying database.
|
||
</p>
|
||
<p>
|
||
The <code class="methodname">DB->set_errpfx()</code> method may be called at any time during the life
|

of the application.
