<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<p><strong>uaddr2taddr()</strong> translates the universal address pointed to
|
||
|
|
by <em>addr</em> and returns a pointer to a netbuf structure.</p>
|
||
|
|
|
||
|
|
<p>It is the caller's responsibility to free the returned netbuf structure when
|
||
|
|
done using the <strong>netdir_free()</strong> function.</p>
|
||
|
|
|
||
|
