FUTIMESAT(2) Linux Programmer's Manual FUTIMESAT(2)
futimesat - change timestamps of a file relative to a directory file descrip-
tor
#define _ATFILE_SOURCE
#include <fcntl.h> /* Definition of AT_* constants */
int futimesat(int dirfd, const char *pathname,
const struct timeval times[2]);
This system call is obsolete.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.
On success, futimesat() 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 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.
futimesat() was added to Linux in kernel 2.6.16.
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.
If pathname is NULL, then the glibc futimesat() wrapper function updates the
times for the file referred to by dirfd.
