futimesat - change timestamps of a file relative to a directory file descriptor
#include <fcntl.h> /* Definition of AT_* constants */
#include <sys/time.h>
int futimesat(int dirfd, const char *pathname,
const struct timeval times[2]);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
futimesat(): _GNU_SOURCE
This system call is obsolete.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.
futimesat() was added to Linux in kernel 2.6.16; library support was added to glibc in version 2.4.
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.
If pathname
is NULL, then the glibc futimesat() wrapper function updates the times for the file referred to by dirfd
.
