DESCRIPTION
This system call is obsolete. Use utimensat(2) instead.
The futimesat() system call
operates in exactly the same way as utimes(2), except for the
differences described in this manual page.
If the pathname given in pathname is relative, then it
is interpreted relative to the directory referred to by the
file descriptor dirfd
(rather than relative to the current working directory of the
calling process, as is done by utimes(2) for a relative
pathname).
If pathname is
relative and dirfd is
the special value AT_FDCWD,
then pathname is
interpreted relative to the current working directory of the
calling process (like utimes(2)).
If pathname is
absolute, then dirfd
is ignored.
RETURN VALUE
On success, futimesat()
returns a 0. On error, −1 is returned and errno is set to indicate the error.
ERRORS
The same errors that occur for utimes(2) can also occur
for futimesat(). The following
additional errors can occur for futimesat():
- EBADF
-
dirfdis not a valid file descriptor. - ENOTDIR
-
pathnameis relative anddirfdis a file descriptor referring to a file other than a directory.
VERSIONS
futimesat() was added to
Linux in kernel 2.6.16; library support was added to glibc in
version 2.4.
CONFORMING TO
This system call is nonstandard. It was implemented from a specification that was proposed for POSIX.1, but that specification was replaced by the one for utimensat(2).
A similar system call exists on Solaris.
