<p>The <em>inet_makeaddr()</em> function is used to generate a 32-bit IP
|
||
|
|
address from the 32-bit network IP address and the local address of the
|
||
|
|
host.</p>
|
||
|
|
|
||
|
|
<p>There are two versions of
|
||
|
|
the API, as shown above. The base i5/OS API uses BSD 4.3 structures and
|
||
|
|
syntax. The other uses syntax and structures compatible with the UNIX 98
|
||
|
|
programming interface specifications. You can select the UNIX 98 compatible
|
||
|
|
interface with the <a href="_xopen_source.htm">_XOPEN_SOURCE</a> macro.</p>
|
||
|
|

<h3>Parameters</h3>
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><strong>network_address</strong></dt>
|
||
|
|
|
||
|
|
<dd>(Input) The 32-bit network IP address.<br>
|
||
|
|
<br>
|
||
|
|
</dd>
|
||
|
|
|
||
|
|
<dt><strong>host_address</strong></dt>
|
||
|
|
|
||
|
|
<dd>(Input) The local host address.</dd>
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<br>
|
||
|
|

<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>No authorization is required.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>Return Value</h3>
|
||
|
|
|
||
|
|
<p><em>inet_makeaddr()</em> returns an integer. Possible values are:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>n (where n is the 32-bit IP address)</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<p>When you develop in C-based languages and an application is compiled with the _XOPEN_SOURCE
|
||
|
|
macro defined to the value 520 or greater, the <em>inet_makeaddress()</em> API is mapped to
|
||
|
|
<em>qso_inet_makeaddress98()</em>.</p>
