<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <stdio.h>
|
||
|
|
int rename(const char *<var>old</var>, const char *<var>new</var>);
|
||
|
|
|
||
|

</pre></div>
|
||
|
|
<p><strong>Description</strong><br>
|
||
|
|
Use <code>rename</code> to establish a new name (the string at <var>new</var>) for a
|
||
|
|
file now known by the string at <var>old</var>. After a successful
|
||
|
|
<code>rename</code>, the file is no longer accessible by the string at <var>old</var>.
|
||
|
|
</p>
|
||
|
|
<p>If <code>rename</code> fails, the file named <code>*<var>old</var></code> is unaffected. The
|
||
|
|
conditions for failure depend on the host operating system.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
The result is either <code>0</code> (when successful) or <code>-1</code> (when the file
|
||
|
|
could not be renamed).
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
ANSI C requires <code>rename</code>, but only specifies that the result on
|
||
|
|
failure be nonzero. The effects of using the name of an existing file
|
||
|
|
as <code>*<var>new</var></code> may vary from one implementation to another.
|
||
|
|
</p>
|
||
|
|
<p>Supporting OS subroutines required: <code>link</code>, <code>unlink</code>, or <code>rename</code>.
|
||
|
|
