<title>DESCRIPTION</title>
<para>
<function>lwres_net_ntop()</function> converts an IP address of
protocol family <parameter>af</parameter> — IPv4 or IPv6 —
at location <parameter>src</parameter> from network format to its
conventional representation as a string. For IPv4 addresses, that
string would be a dotted-decimal. An IPv6 address would be
represented in colon notation as described in RFC1884.
</para>
<para>
The generated string is copied to <parameter>dst</parameter> provided
<parameter>size</parameter> indicates it is long enough to store the
ASCII representation of the address.
</para>
</refsect1>
<refsect1>
<title>RETURN VALUES</title>
<para>
If successful, the function returns <parameter>dst</parameter>:
a pointer to a string containing the presentation format of the
address. <function>lwres_net_ntop()</function> returns
<type>NULL</type> and sets the global variable
<constant>errno</constant> to <errorcode>EAFNOSUPPORT</errorcode> if
the protocol family given in <parameter>af</parameter> is not
supported.
