<refsection><info><title>DESCRIPTION</title></info>

<para><function>lwres_net_ntop()</function>

converts an IP address of protocol family

<parameter>af</parameter> &mdash; IPv4 or IPv6 &mdash; 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>

</refsection>

<refsection><info><title>RETURN VALUES</title></info>

<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.
