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>>. |
