| <h3 class="section">4.52 <code>rename</code>—rename a file</h3> |
| |
| <p><a name="index-rename-260"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <stdio.h> |
| int rename(const char *<var>old</var>, const char *<var>new</var>); |
| |
| </pre> |
| <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>If <code>rename</code> fails, the file named <code>*</code><var>old</var> is unaffected. The |
| conditions for failure depend on the host operating system. |
| |
| <p><br> |
| <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> |
| <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>*</code><var>new</var> may vary from one implementation to another. |
| |
| <p>Supporting OS subroutines required: <code>link</code>, <code>unlink</code>, or <code>rename</code>. |
