<p>Your NEW problem is one of precedence. <code>+</code> has higher precedence than <code>&lt;&lt;</code> so your statement is parsed like <code>value = value_high &lt;&lt; (18 + value_low)</code>.</p> <p>To solve this, add parentheses explicitly, like: <code>value = (value_high &lt;&lt; 18) + value_low</code>.</p>

What are the semantics of fdatasync() when used on a directory descriptor?<p>Specifically, can <code>fdatasync</code> be used in place of <code>fsync</code> if I only care about the directory structure and not timestamps or other directory metadata. If it can, does it have any performance advantages?</p> <p>Does POSIX ...
<p>Think of it from the point of view of the VFS API, it's generally implemented as: sync content + optionally metadata. In a directory it means: sync some of children metadata + optionally it's own metadata.</p> <p>However, ultimately, how to handle it, is up to the file system.</p> <p>If the attributes metadata is pa...
