NAME

remove - remove a file

SYNOPSIS

`#include <stdio.h>

int remove(const char *

path);
`

DESCRIPTION

[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.

The remove() function shall cause the file named by the pathname pointed to by path to be no longer accessible by that name. A subsequent attempt to open that file using that name shall fail, unless it is created anew.

[CX] If_path_ does not name a directory, remove(path) shall be equivalent to unlink(path).

If path names a directory, remove(path) shall be equivalent to rmdir(path).

RETURN VALUE

[CX] Refer to rmdir() or unlink().

ERRORS

[CX] Refer to rmdir() or unlink().

The following sections are informative.

EXAMPLES

CHANGE HISTORY

First released in Issue 3. Included for alignment with the POSIX.1-1988 standard and the ISO C standard.

Issue 6

Extensions beyond the ISO C standard are marked.

The following new requirements on POSIX implementations derive from alignment with the Single UNIX Specification:

• The DESCRIPTION, RETURN VALUE, and ERRORS sections are updated so that if path is not a directory, remove() is equivalent to unlink(), and if it is a directory, it is equivalent to rmdir().
