<h4><a name="tag_03_137_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>fchdir</i>() function shall be equivalent to <a href="../functions/chdir.html"><i>chdir</i>()</a> except that the
|
|
directory that is to be the new current working directory is specified by the file descriptor <i>fildes</i>.</p>
|
|
|
|
<p>A conforming application can obtain a file descriptor for a file of type directory using <a href=
|
|
"../functions/open.html"><i>open</i>()</a>, provided that the file status flags and access modes do not contain O_WRONLY or
|
|
O_RDWR.</p>
|
|
</blockquote>
|
|
|
|
<h4><a name="tag_03_137_04"></a>RETURN VALUE</h4>
|
|
|
|
<blockquote>
|
|
<p>Upon successful completion, <i>fchdir</i>() shall return 0. Otherwise, it shall return -1 and set <i>errno</i> to indicate the
|
|
error. On failure the current working directory shall remain unchanged.</p>
