 70
 71    <para><function>lwres_net_ntop()</function>
 72      converts an IP address of protocol family
 73      <parameter>af</parameter> &mdash; IPv4 or IPv6 &mdash; at
 74      location <parameter>src</parameter> from network format to its
 75      conventional representation as a string.  For IPv4 addresses,
 76      that string would be a dotted-decimal.  An IPv6 address would be
 77      represented in colon notation as described in RFC1884.
 78    </para>
 79
 80    <para>
 81      The generated string is copied to <parameter>dst</parameter>
 82      provided
 83      <parameter>size</parameter> indicates it is long enough to
 84      store the
 85      ASCII representation of the address.

 91
 92    <para>
 93      If successful, the function returns <parameter>dst</parameter>:
 94      a pointer to a string containing the presentation format of the
 95      address.  <function>lwres_net_ntop()</function> returns
 96      <type>NULL</type> and sets the global variable
 97      <constant>errno</constant> to <errorcode>EAFNOSUPPORT</errorcode> if
 98      the protocol family given in <parameter>af</parameter> is
 99      not
100      supported.
