<p><strong>Synopsis</strong>

|
|
</p><div class="example">

|
<pre class="example">#include <stdio.h>
|
||
|
|
int remove(char *<var>filename</var>);
|
||
|
|
|
||
|
|
int _remove_r(struct _reent *<var>reent</var>, char *<var>filename</var>);

|
|

</pre></div>
|

|
|
<p><strong>Description</strong><br>
|
||
|
|
Use <code>remove</code> to dissolve the association between a particular
|
||
|
|
filename (the string at <var>filename</var>) and the file it represents.
|
||
|
|
After calling <code>remove</code> with a particular filename, you will no
|
||
|
|
longer be able to open the file by that name.
|
||
|
|
</p>
|
||
|
|
<p>In this implementation, you may use <code>remove</code> on an open file without
|
||
|
|
error; existing file descriptors for the file will continue to access
|
||
|
|
the file’s data until the program using them closes the file.
|
||
|
|
</p>
|
||
|
|
<p>The alternate function <code>_remove_r</code> is a reentrant version. The
|
||
|
|
extra argument <var>reent</var> is a pointer to a reentrancy structure.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
<code>remove</code> returns <code>0</code> if it succeeds, <code>-1</code> if it fails.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
ANSI C requires <code>remove</code>, but only specifies that the result on
|
||
|
|
failure be nonzero. The behavior of <code>remove</code> when you call it on an
|
||
|
|
open file may vary among implementations.
|
||
|
|
</p>
|
||
|
|
<p>Supporting OS subroutine required: <code>unlink</code>.

||
