<description>
<p>The module <c>snmp_view_based_acm_mib</c> implements the instrumentation functions for the
SNMP-VIEW-BASED-ACM-MIB, and functions for configuring the database.
</p>
<p>The configuration files are described in the SNMP User's Manual.</p>

<funcs>
<func>
<name>configure(ConfDir) -> void()</name>
<fsummary>Configure the SNMP-VIEW-BASED-ACM-MIB</fsummary>
<type>
<v>ConfDir = string()</v>
</type>
<desc>
<p>This function is called from the supervisor at system
start-up. </p>
<p>Inserts all data in the configuration files into the
database and destroys all old rows with StorageType
<c>volatile</c>. The rows created from the configuration file
will have StorageType <c>nonVolatile</c>. </p>
<p>All <c>snmp</c> counters are set to zero. </p>
<p>If an error is found in the configuration file, it is
reported using the function <c>config_err/2</c> of the error
report module, and the function fails with the reason
<c>configuration_error</c>. </p>
<p><c>ConfDir</c> is a string which points to the directory
where the configuration files are found. </p>
<p>The configuration file read is: <c>vacm.conf</c>. </p>
<marker id="reconfigure"></marker>

</func>
<func>
<name>reconfigure(ConfDir) -> void()</name>
<fsummary>Configure the SNMP-VIEW-BASED-ACM-MIB</fsummary>
<type>
<v>ConfDir = string()</v>
</type>
<desc>
<p>Inserts all data in the configuration files into the
database and destroys all old data, including the rows with
StorageType <c>nonVolatile</c>. The rows created from the
configuration file will have StorageType <c>nonVolatile</c>.
</p>
<p>Thus, the data in the SNMP-VIEW-BASED-ACM-MIB, after this
function has been called, is the data from the configuration
files.
</p>
<p>All <c>snmp</c> counters are set to zero.
</p>
<p>If an error is found in the configuration file, it is
reported using the function
<seealso marker="snmpa_error#config_err">config_err/2</seealso>
of the error report module, and the function fails with the reason
<c>configuration_error</c>.
</p>
<p><c>ConfDir</c> is a string which points to the directory
where the configuration files are found.
</p>
<p>The configuration file read is: <c>vacm.conf</c>. </p>
