FUTIMESAT(2)		   Linux Programmers Manual		 FUTIMESAT(2)



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

SYNOPSIS
       #define _ATFILE_SOURCE
       #include  /* Definition of AT_* constants */

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

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       This system call is obsolete.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 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.

CONFORMING TO
       This system call is non-standard.  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
       updates the times for the file referred to by dirfd.
