futimesat(2)               System Calls Manual              futimesat(2)

NAME

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

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

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

       [[deprecated]] 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       This system call is obsolete.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.  (See openat(2)
       for an explanation of why the dirfd argument is useful.)

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  pathname is relative but dirfd is neither AT_FDCWD nor a
              valid file descriptor.

       ENOTDIR
              pathname is relative and dirfd is a file descriptor
              referring to a file other than a directory.

VERSIONS

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

STANDARDS

       None.

HISTORY

       Linux 2.6.16, glibc 2.4.

       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.
