ANSI_SYNOPSIS
|
| 26 |
|
|
#include <stdio.h>
|
| 27 |
|
|
int rename(const char *<[old]>, const char *<[new]>);
|
| 28 |
|
|
|

|
|
TRAD_SYNOPSIS
|
| 30 |
|
|
#include <stdio.h>
|
| 31 |
|
|
int rename(<[old]>, <[new]>)
|
| 32 |
|
|
char *<[old]>;
|
| 33 |
|
|
char *<[new]>;
|
| 34 |
|
|
|
| 35 |
|
|
DESCRIPTION
|
| 36 |
|
|
Use <<rename>> to establish a new name (the string at <[new]>) for a
|
| 37 |
|
|
file now known by the string at <[old]>. After a successful
|
| 38 |
|
|
<<rename>>, the file is no longer accessible by the string at <[old]>.
|
| 39 |
|
|
|
| 40 |
|
|
If <<rename>> fails, the file named <<*<[old]>>> is unaffected. The
|
| 41 |
|
|
conditions for failure depend on the host operating system.
|
| 42 |
|
|
|
| 43 |
|
|
RETURNS
|
| 44 |
|
|
The result is either <<0>> (when successful) or <<-1>> (when the file
|
| 45 |
|
|
could not be renamed).
|
| 46 |
|
|
|
| 47 |
|
|
PORTABILITY
|
| 48 |
|
|
ANSI C requires <<rename>>, but only specifies that the result on
|
| 49 |
|
|
failure be nonzero. The effects of using the name of an existing file
|
| 50 |
|
|
as <<*<[new]>>> may vary from one implementation to another.
|
| 51 |
|
|
|
| 52 |
|
|
Supporting OS subroutines required: <<link>>, <<unlink>>, or <<rename>>.
