<p>The module <c>snmpa_error</c> contains two callback functions
which are called if an error occurs at different times during agent
operation. These functions in turn calls the corresponding function
in the configured error report module, which implements the actual
report functionality.
</p>
<p>Two simple implementation(s) is provided with the
toolkit; the modules
<seealso marker="snmpa_error_logger">snmpa_error_logger</seealso>
which is the default and
<seealso marker="snmpa_error_io">snmpa_error_io</seealso>.
</p>
<p>The error report module is configured using the directive
<c>error_report_mod</c>, see
<seealso marker="snmp_config#configuration_params">configuration parameters</seealso>.
