  <description>
    <marker id="desc"></marker>
    <p>This module defines the behaviour of the agent error reporting.
      A <c>snmpa_error_report</c> compliant module 
      must export the following functions: </p>
    <list type="bulleted">
      <item>
        <p>config_err/2</p>
      </item>
      <item>
        <p>user_err/2</p>
      </item>
    </list>
    <p>The semantics of them and their exact signatures are explained
      below. </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>
      </desc>
