<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<p><strong>taddr2uaddr()</strong> translates the address pointed to by
|
||
|
|
<em>addr</em> and returns a transport independent character representation of
|
||
|
|
the address (universal address).</p>
|
||
|
|
|
||
|
|
<p>The caller is responsible to free the returned universal address when
|
||
|
|
done.</p>
|
||
|
|
|
||
|
|

||
