NAME

       futimesat - change timestamps of a file relative to a directory file descriptor

SYNOPSIS

       #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

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       This system call is obsolete.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  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; 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.

NOTES

   Glibc notes
       If  pathname is NULL, then the glibc futimesat() wrapper function updates the times for the file referred
       to by dirfd.
