<h4><a name="tag_03_217_12"></a>Issue 6</h4>

|
|
|
<blockquote>
|
|
<p>In the SYNOPSIS, the optional include of the <a href="../basedefs/sys/types.h.html"><i><sys/types.h></i></a> header is
|
|
removed.</p>
|
|
|
|
<p>The following new requirements on POSIX implementations derive from alignment with the Single UNIX Specification:</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p>The requirement to include <a href="../basedefs/sys/types.h.html"><i><sys/types.h></i></a> has been removed. Although <a
|
|
href="../basedefs/sys/types.h.html"><i><sys/types.h></i></a> was required for conforming implementations of previous POSIX
|
|
specifications, it was not required for UNIX applications.</p>
|
|
</li>

</ul>
