<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>
<br>
<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>
