    <title>DESCRIPTION</title>

    <para><function>lwres_conf_init()</function>
      creates an empty
      <type>lwres_conf_t</type>
      structure for lightweight resolver context
      <parameter>ctx</parameter>.
    </para>

    <para><function>lwres_conf_clear()</function>
      frees up all the internal memory used by
      that
      <type>lwres_conf_t</type>
      structure in resolver context
      <parameter>ctx</parameter>.
    </para>

    <para><function>lwres_conf_parse()</function>
      opens the file
      <parameter>filename</parameter>
      and parses it to initialise the resolver context
      <parameter>ctx</parameter>'s
      <type>lwres_conf_t</type>
      structure.
    </para>

    <para><function>lwres_conf_print()</function>
      prints the
      <type>lwres_conf_t</type>
      structure for resolver context
      <parameter>ctx</parameter>
      to the
      <type>FILE</type>
      <parameter>fp</parameter>.
    </para>

  <refsect1>

    <title>RETURN VALUES</title>

    <para><function>lwres_conf_parse()</function>
      returns <errorcode>LWRES_R_SUCCESS</errorcode>
      if it successfully read and parsed
      <parameter>filename</parameter>.
      It returns <errorcode>LWRES_R_FAILURE</errorcode>
      if <parameter>filename</parameter>
      could not be opened or contained incorrect
      resolver statements.
    </para>

    <para><function>lwres_conf_print()</function>
      returns <errorcode>LWRES_R_SUCCESS</errorcode>
      unless an error occurred when converting the network addresses to a
      numeric host address string.
      If this happens, the function returns
      <errorcode>LWRES_R_FAILURE</errorcode>.
