FUTIMESAT(2)                                        Linux Programmer's Manual                                       FUTIMESAT(2)



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

SYNOPSIS
       #include <fcntl.h> /* Definition of AT_* constants */

       int futimesat(int dirfd, const char *pathname,
                     const struct timeval times[2]);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       futimesat():
       Since glibc 2.10: _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
       Before glibc 2.10: _ATFILE_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       This system call is obsolete.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.

CONFORMING TO
       This system call is nonstandard.  It was implemented from a specification that was proposed for POSIX.1, but that  speci-
       fication 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.
