FUNCTION
|
|
<<rename>>---rename a file
|
|
|
|
INDEX
|
|
rename
|
|
|
|
SYNOPSIS
|
|
#include <stdio.h>
|
|
int rename(const char *<[old]>, const char *<[new]>);
|
|
|
|
DESCRIPTION
|
|
Use <<rename>> to establish a new name (the string at <[new]>) for a
|
|
file now known by the string at <[old]>. After a successful
|
|
<<rename>>, the file is no longer accessible by the string at <[old]>.
|
|
|
|
If <<rename>> fails, the file named <<*<[old]>>> is unaffected. The
|
|
conditions for failure depend on the host operating system.
|
|
|
|
RETURNS
|
|
The result is either <<0>> (when successful) or <<-1>> (when the file
|
|
could not be renamed).
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<rename>>, but only specifies that the result on
|
|
failure be nonzero. The effects of using the name of an existing file
|
|
as <<*<[new]>>> may vary from one implementation to another.
|
|
|
|
Supporting OS subroutines required: <<link>>, <<unlink>>, or <<rename>>.
