This system call is obsolete. Use utimensat(2) instead.
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
(rather than relative to the current working directory of the
calling process, as is done by utimes(2) for a relative
the special value
interpreted relative to the current working directory of the
calling process (like utimes(2)).
returns a 0. On error, −1 is returned and
errno is set to indicate the error.
The same errors that occur for utimes(2) can also occur
futimesat(). The following
additional errors can occur for
dirfdis not a valid file descriptor.
pathnameis relative and
dirfdis a file descriptor referring to a file other than a directory.
futimesat() was added to
Linux in kernel 2.6.16; library support was added to glibc in
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.
