<b>Description: DB_ENV-&gt;err</b>
<p>The DB_ENV-&gt;err, DB_ENV-&gt;errx, <a href="../api_c/db_err.html">DB-&gt;err</a> and
<a href="../api_c/db_err.html">DB-&gt;errx</a> methods provide error-messaging functionality for
applications written using the Berkeley DB library.</p>
<p>The <a href="../api_c/db_err.html">DB-&gt;err</a> and DB_ENV-&gt;err methods constructs an error message
consisting of the following elements:</p>
<blockquote><br>
<b>An optional prefix string</b><ul compact><li>If no error callback function has been set using the
<a href="../api_c/env_set_errcall.html">DB_ENV-&gt;set_errcall</a> method, any prefix string specified using the
<a href="../api_c/env_set_errpfx.html">DB_ENV-&gt;set_errpfx</a> method, followed by two separating characters: a colon
and a &lt;space&gt; character.</ul>
<b>An optional printf-style message</b><ul compact><li>The supplied message <b>fmt</b>, if non-NULL, in which the
ANSI C X3.159-1989 (ANSI C) printf function specifies how subsequent parameters
are converted for output.</ul>
<b>A separator</b><ul compact><li>Two separating characters: a colon and a &lt;space&gt; character.</ul>
<b>A standard error string</b><ul compact><li>The standard system or Berkeley DB library error string associated with the
<b>error</b> value, as returned by the <a href="../api_c/env_strerror.html">db_strerror</a> method.</ul>
<br>
</blockquote>
<p>The <a href="../api_c/db_err.html">DB-&gt;errx</a> and DB_ENV-&gt;errx methods are the same as the
<a href="../api_c/db_err.html">DB-&gt;err</a> and DB_ENV-&gt;err methods, except they do not append the
final separator characters and standard error string to the error
message.</p>
<p>This constructed error message is then handled as follows:</p>
<blockquote><p>If an error callback function has been set (see <a href="../api_c/db_set_errcall.html">DB-&gt;set_errcall</a>
and <a href="../api_c/env_set_errcall.html">DB_ENV-&gt;set_errcall</a>), that function is called with two
parameters: any prefix string specified (see <a href="../api_c/db_set_errpfx.html">DB-&gt;set_errpfx</a> and
<a href="../api_c/env_set_errpfx.html">DB_ENV-&gt;set_errpfx</a>) and the error message.</p>
<p>If a C library FILE * has been set (see <a href="../api_c/db_set_errfile.html">DB-&gt;set_errfile</a> and
<a href="../api_c/env_set_errfile.html">DB_ENV-&gt;set_errfile</a>), the error message is written to that output
stream.</p>
<p>If none of these output options has been configured, the error message
is written to stderr, the standard error output stream.</p></blockquote>
<b>Parameters</b> <br>
<b>error</b><ul compact><li>The <b>error</b> parameter is the error value for which the
DB_ENV-&gt;err and <a href="../api_c/db_err.html">DB-&gt;err</a> methods will display a explanatory
string.</ul>
<b>fmt</b><ul compact><li>The <b>fmt</b> parameter is an optional printf-style message to display.</ul>
