    <title>DESCRIPTION</title>
    <para>
      The <function>pam_syslog</function> function logs messages using
      <citerefentry>
        <refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum>
      </citerefentry> and is intended for internal use by Linux-PAM and
      PAM service modules. The <emphasis>priority</emphasis> argument is
      formed by ORing the facility and the level values as documented
      in the <citerefentry>
        <refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum>
      </citerefentry> manual page.
    </para>
    <para>
      The <function>pam_vsyslog</function> function performs the same
      task as <function>pam_syslog()</function> with the difference
      that it takes a set of arguments which have been obtained using
      the <citerefentry>
        <refentrytitle>stdarg</refentrytitle><manvolnum>3</manvolnum>
      </citerefentry> variable argument list macros.
