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 */
       #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       This system call	is obsolete.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  er-
       rno is set to indicate the error.

ERRORS
       The  same  errors  that	occur for utimes(2) can	also occur for futime-
       sat().  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  specifica-
       tion 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  up-
       dates the times for the file referred to	by dirfd.
