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>>.
