2086N/A<
p><
code class="function">lwres_net_ntop()</
code>
2086N/A converts an IP address of protocol family
2086N/A <
em class="parameter"><
code>af</
code></
em> — IPv4 or IPv6 — at
2086N/A location <
em class="parameter"><
code>src</
code></
em> from network format to its
2086N/A conventional representation as a string. For IPv4 addresses,
2086N/A that string would be a dotted-decimal. An IPv6 address would be
2086N/A represented in colon notation as described in RFC1884.
2086N/A The generated string is copied to <
em class="parameter"><
code>dst</
code></
em>
2086N/A <
em class="parameter"><
code>size</
code></
em> indicates it is long enough to
2086N/A ASCII representation of the address.

h2>RETURN VALUES</

2086N/A If successful, the function returns <

em>:
2960N/A a pointer to a string containing the presentation format of the
2086N/A address. <
