|
||
|
||
|
||
<p><code class="function">lwres_net_ntop()</code>
|
||
converts an IP address of protocol family
|
||
<em class="parameter"><code>af</code></em> — IPv4 or IPv6 — at
|
||
location <em class="parameter"><code>src</code></em> 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.
|
||
</p>
|
||
|
||
<p>
|
||
The generated string is copied to <em class="parameter"><code>dst</code></em>
|
||
provided
|
||
<em class="parameter"><code>size</code></em> indicates it is long enough to
|
||
store the
|
||
ASCII representation of the address.
|
||
</p>
|
||
|
||
</div>
|
||
<div class="refsection">
|
||
<a name="id-1.8"></a><h2>RETURN VALUES</h2>
|
||
|
||
|
||
<p>
|
||
If successful, the function returns <em class="parameter"><code>dst</code></em>:
|
||
a pointer to a string containing the presentation format of the
|
||
address. <code class="function">lwres_net_ntop()</code> returns
|
||
<span class="type">NULL</span> and sets the global variable
|
||
<code class="constant">errno</code> to <span class="errorcode">EAFNOSUPPORT</span> if
|
||
the protocol family given in <em class="parameter"><code>af</code></em> is
|
||
not
|
||
supported.
