<h1>9 Manager Implementation Example</h1>
<p>This <strong>Implementation Example</strong> section describes
how a simple manager can be implemented with the
SNMP Development Toolkit. </p>
<p>The example shown, <strong>ex2</strong>, can be found in the toolkit
distribution. </p>
<p>This example has two functions: </p>
<ul>
<li>
<p>A simple example of how to use the manager component of
the SNMP Development Toolkit.</p>
</li>
<li>
<p>A simple example of how to write agent test cases, using the new
manager.</p>
</li>
</ul>
<h3><a name="id82242">9.1
The example manager</a></h3>
<p>The example manager, <span class="code">snmp_ex2_manager</span>, is a simple example of
how to implement an snmp manager using the manager component of the
SNMP Development Toolkit.</p>
<p>The module exports the following functions:</p>
<ul>
<li>
<p>start_link/0, start_link/1</p>
</li>
<li>
<p>stop/0</p>
</li>
<li>
<p>agent/2, agent/3</p>
</li>
<li>
<p>sync_get/2, sync_get/3</p>
</li>
<li>
<p>sync_get_next/2, sync_get_next/3</p>
</li>
<li>
<p>sync_get_bulk/4, sync_get_bulk/5</p>
</li>
<li>
<p>sync_set/2, sync_set/3</p>
</li>
<li>
<p>oid_to_name/1</p>
</li>
</ul>
<p>This module is also used by the test module described in the
next section.</p>
<h3><a name="id82333">9.2
A simple standard test</a></h3>
<p>This simple standard test, <span class="code">snmp_ex2_simple_standard_test</span>,
a module which, using the <span class="code">snmp_ex2_manager</span> described in the
previous section, implements a simple agent test utility. </p>
