13 int newdirfd, const char *newpath);

15 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
16
17 renameat():
18 Since glibc 2.10:
19 _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
20 Before glibc 2.10:
21 _ATFILE_SOURCE
22
24 The renameat() system call operates in exactly the same way as
25 rename(2), except for the differences described in this manual page.
26
27 If the pathname given in oldpath is relative, then it is interpreted
28 relative to the directory referred to by the file descriptor olddirfd
29 (rather than relative to the current working directory of the calling
30 process, as is done by rename(2) for a relative pathname).
31
32 If oldpath is relative and olddirfd is the special value AT_FDCWD, then
33 oldpath is interpreted relative to the current working directory of the
34 calling process (like rename(2)).
35
36 If oldpath is absolute, then olddirfd is ignored.
37
38 The interpretation of newpath is as for oldpath, except that a relative
39 pathname is interpreted relative to the directory referred to by the
40 file descriptor newdirfd.
41
43 On success, renameat() returns 0. On error, -1 is returned and errno
44 is set to indicate the error.
45
47 The same errors that occur for rename(2) can also occur for renameat().
48 The following additional errors can occur for renameat():
49
50 EBADF olddirfd or newdirfd is not a valid file descriptor.
51
52 ENOTDIR
53 oldpath is relative and olddirfd is a file descriptor referring
54 to a file other than a directory; or similar for newpath and
55 newdirfd
56
58 renameat() was added to Linux in kernel 2.6.16; library support was
59 added to glibc in version 2.4.
60
62 POSIX.1-2008.

65 See openat(2) for an explanation of the need for renameat().
