19 FUNCTION
20 <<rename>>---rename a file
21
22 INDEX
23 rename
24
25 SYNOPSIS
26 #include <stdio.h>
27 int rename(const char *<[old]>, const char *<[new]>);
28
29 DESCRIPTION
30 Use <<rename>> to establish a new name (the string at <[new]>) for a
31 file now known by the string at <[old]>. After a successful
32 <<rename>>, the file is no longer accessible by the string at <[old]>.
33
34 If <<rename>> fails, the file named <<*<[old]>>> is unaffected. The
35 conditions for failure depend on the host operating system.
36
37 RETURNS
38 The result is either <<0>> (when successful) or <<-1>> (when the file
39 could not be renamed).
40
41 PORTABILITY
42 ANSI C requires <<rename>>, but only specifies that the result on
43 failure be nonzero. The effects of using the name of an existing file
44 as <<*<[new]>>> may vary from one implementation to another.
45
46 Supporting OS subroutines required: <<link>>, <<unlink>>, or <<rename>>.
