<modulesummary>Functions for Reporting SNMP Errors on stdio</modulesummary>
<description>
<p>The module <c>snmpa_error_io</c> implements the
<c>snmp_error_report</c> behaviour
(see <seealso marker="snmpa_error_report">snmpa_error_report</seealso>)
containing two callback functions which are called in order to
report SNMP errors.
</p>
<p>This module provides a simple mechanism for reporting SNMP
errors. Errors are written to stdout using the <c>io</c> module.
It is provided as an simple example.
</p>
<p>This module needs to be explicitly configured, see
<seealso marker="snmpa_error#desc">snmpa_error</seealso> and
<seealso marker="snmp_config#configuration_params">configuration parameters</seealso>.
</p>
</description>
<funcs>
<func>
<name>config_err(Format, Args) -> void()</name>
<fsummary>Called if a configuration error occurs</fsummary>
<type>
<v>Format = string()</v>
<v>Args = list()</v>
</type>
<desc>
<p>The function is called if an error occurs during the
configuration phase, for example if a syntax error is found in
a configuration file.
</p>
<p><c>Format</c> and <c>Args</c> are as in
<c>io:format(Format, Args)</c>.</p>
</desc>
</func>
<func>
<name>user_err(Format, Args) -> void()</name>
<fsummary>Called if a user related error occurs</fsummary>
<type>
<v>Format = string()</v>
<v>Args = list()</v>
</type>
<desc>
<p>The function is called if a user related error occurs at
run-time, for example if a user defined instrumentation
function returns erroneous.
</p>
<p><c>Format</c> and <c>Args</c> are as in
<c>io:format(Format, Args)</c>.</p>
