FUNCTION
<<rename>>---rename a file
INDEX
rename
INDEX
_rename_r
ANSI_SYNOPSIS
#include <stdio.h>
int rename(const char *<[old]>, const char *<[new]>);
int _rename_r(struct _reent *<[reent]>,
const char *<[old]>, const char *<[new]>);
TRAD_SYNOPSIS
#include <stdio.h>
int rename(<[old]>, <[new]>)
char *<[old]>;
char *<[new]>;
int _rename_r(<[reent]>, <[old]>, <[new]>)
struct _reent *<[reent]>;
char *<[old]>;
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.
The alternate function <<_rename_r>> is a reentrant version. The
extra argument <[reent]> is a pointer to a reentrancy structure.
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>>.
