<h3>Description</h3>
|
|
<p>
|
|
<tt>mkdir</tt> creates a directory named <em>name</em>, where
|
|
<em>name</em> is the last filename component in <em>pathname</em>. All
|
|
the directories named in the prefix portion of <em>pathname</em> must
|
|
exist and must in fact be directories, not ordinary files. The name
|
|
<em>name</em> must not already exist. The new directory must be
|
|
created atomically.
|
|
</p>
|
|
|
|
<p>
|
|
The <em>mode</em> argument gives the file permissions to use and can
|
|
be ignored in OS/161.
|
|
</p>
|
|
|
|
<h3>Return Values</h3>
|
|
<p>
|
|
On success, <tt>mkdir</tt> returns 0. On error, -1 is returned, and
|
|
<A HREF=errno.html>errno</A> is set according to the error
|
|
encountered.
|
|
</p>
|
|
|
|
<h3>Errors</h3>
|
