<h3>Return Value</h3>
|
|
|
|
<p>The <em>ns_ntoa_r()</em> function returns:</p>
|
|
|
|
<ul>
|
|

<h3>Error Conditions</h3>
|
|
|
|
<p>When the <em>ns_ntoa_r()</em> function fails, <em>errno</em> can be set
|
|
to:</p>
|
|
|
|
<dl>
|
|
<dt><em>[EINVAL]</em></dt>
|
|
<dd><p>Parameter is not valid.</p>
|
|
|
|
<p>This error code indicates one of the following:</p>
|
|
|
|
<ul>
|
|
<li>The <em>output_buffer_length</em> length is less than 35.</li>
|
|
</ul>
|
|
</dd>
|
|
</dl>
|
|
<br>
|

<h3>Usage Notes</h3>
|
|
|
|
<ol>
|
|
<li>The network services address consists of three fields, the network field,
|
|
the host field, and the port number field. <em>ns_ntoa_r()</em> will return
|
|
these fields as a single character string with the fields separated by the
|
|
period (.) character. The character string is always terminated with a NULL
|
|
character.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>The fields are always returned in hexadecimal notation.
|
|
<em>ns_ntoa_r()</em> will insert an 'H' character at the end of each field that
|
|
does not contain an a,b,c,d,e,f,A,B,C,D,E or F character, in order to make it
|
|
obvious that the notation is in hexadecimal.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>Not all fields need be returned. For example, if the host field and the
|
|
port number field of the network services address both contain hexadecimal
|
|
zeros, the <em>ns_ntoa_r()</em> routine will return a character string that
|
|
only contains the network field.</li>
|
|
</ol>
