This system call is obsolete.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
dirfd
is not a valid file descriptor.
ENOTDIR
pathname
is relative and
dirfd
is a file descriptor referring to a file other than a directory.
VERSIONS
futimesat()
was added to Linux in kernel 2.6.16.
CONFORMING TO
This system call is non-standard.
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.
NOTES
Glibc Notes
If
pathname
is NULL, then the glibc
futimesat()
wrapper function updates the times for the file referred to by
dirfd.
This page is part of release 3.14 of the Linux
man-pages
project.
