13 int futimesat(int dirfd, const char *pathname,
14 const struct timeval times[2]);
15
17 This system call is obsolete. Use utimensat(2) instead.
18
19 The futimesat() system call operates in exactly the same way as
20 utimes(2), except for the differences described in this manual page.
21
22 If the pathname given in pathname is relative, then it is interpreted
23 relative to the directory referred to by the file descriptor dirfd
24 (rather than relative to the current working directory of the calling
25 process, as is done by utimes(2) for a relative pathname).
26
27 If pathname is relative and dirfd is the special value AT_FDCWD, then
28 pathname is interpreted relative to the current working directory of
29 the calling process (like utimes(2)).
30
31 If pathname is absolute, then dirfd is ignored.
32
34 On success, futimesat() returns a 0. On error, -1 is returned and
35 errno is set to indicate the error.
36
38 The same errors that occur for utimes(2) can also occur for futime‐
39 sat(). The following additional errors can occur for futimesat():
40
41 EBADF dirfd is not a valid file descriptor.
42
43 ENOTDIR
44 pathname is relative and dirfd is a file descriptor referring to
45 a file other than a directory.
46
48 futimesat() was added to Linux in kernel 2.6.16.
49
51 This system call is non-standard. It was implemented from a specifica‐
52 tion that was proposed for POSIX.1, but that specification was replaced
53 by the one for utimensat(2).
54
55 A similar system call exists on Solaris.
56
58 Glibc Notes
59 If pathname is NULL, then the glibc futimesat() wrapper function
60 updates the times for the file referred to by dirfd.
