<h4><a name="tag_03_754_03"></a>DESCRIPTION</h4>

<p>The <i>sync</i>() function shall cause all information in memory that updates file systems to be scheduled for writing out to
|
|
all file systems.</p>
|
|
|
|
<p>The writing, although scheduled, is not necessarily complete upon return from <i>sync</i>().</p>
