<h3><a name="tag_01_13"></a>Headers</h3>
|
|
|
|
<h4><a name="tag_01_13_01"></a>Format of Entries</h4>
|
|
|
|
<p>Each header reference page has a common layout of sections describing the interface. This layout is similar to the manual page
|
|
or "man" page format shipped with most UNIX systems, and each header has sections describing the SYNOPSIS and DESCRIPTION. These
|
|
are the two sections that relate to conformance.</p>
|
|
|
|
<p>Additional sections are informative, and add considerable information for the application developer. APPLICATION USAGE sections
|
|
provide additional caveats, issues, and recommendations to the developer. RATIONALE sections give additional information on the
|
|
decisions made in defining the interface.</p>
|
|
|
|
<p>FUTURE DIRECTIONS sections act as pointers to related work that may impact the interface in the future, and often cautions the
|
|
developer to architect the code to account for a change in this area. Note that a future directions statement should not be taken
|
|
as a commitment to adopt a feature or interface in the future.</p>
|
|
|
|
<p>The CHANGE HISTORY section describes when the interface was introduced, and how it has changed.</p>
|
|
|
|
<p>Option labels and margin markings in the page can be useful in guiding the application developer.</p>
