Set the maximum size for the file to be <span class="bold"><strong>gbytes</strong></span> gigabytes plus <span class="bold"><strong>bytes</strong></span>. Attempts to allocate new pages in the
file after the limit has been reached will fail.
</p>
<p>
To set the maximum file size for a particular database, call the
<code class="methodname">DbMpoolFile::set_maxsize()</code> method using the
<a class="link" href="memp.html" title="Chapter 9.  The DbMpoolFile Handle">DbMpoolFile</a> handle stored
in the <span class="bold"><strong>mpf</strong></span> field of the
<a class="link" href="db.html" title="Chapter 2.  The Db Handle">Db</a> handle. Attempts to insert
new items into the database after the limit has been reached may fail.
</p>
<p>
The <code class="methodname">DbMpoolFile::set_maxsize()</code> method configures a file in the
cache, not only operations performed using the specified
<a class="link" href="memp.html" title="Chapter 9.  The DbMpoolFile Handle">DbMpoolFile</a> handle.
</p>
<p>
The <code class="methodname">DbMpoolFile::set_maxsize()</code> method may be called at any time
during the life of the application.
</p>
<p>
The <code class="methodname">DbMpoolFile::set_maxsize()</code> <span>
<span>
method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
