<p>
Since <code>create_symlink()</code>, <code>create_hardlink()</code>, and <code>create_directory()</code> exist, there's
no reason not to have a <code>create_regular_file()</code> function.
</p>
<p>
Consider adding a function <code>create_regular_file()</code> with the behaviour of the POSIX <code>touch</code>
command.
</p>

<p><i>[Beman comments]</i></p>

<p> 
<code>create_regular_file()</code> and <code>touch()</code> should be different functions since
their behavior would differ if the file already exists; touch() updates the last write
date.
</p>

<p>I have often wanted <code>create_regular_file()</code> but never got around to adding it.</p>

<p>While <code>touch</code> is quite useful from the command line, I'm less sure of its usefulness as
a library function. It is trivial for a user to implement.</p>

<p>Whether or not it is appropriate to add operational functions this late in the PDTS
process is questionable.</p>
