NAME
futimesat - change timestamps of a file relative to a directory file descriptor
SYNOPSIS
#define _ATFILE_SOURCE
#include <fcntl.h>
I int futimesat(int dirfd , const char * pathname ,
I const struct timeval times [2]);
DESCRIPTION
The
R 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
R 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
R AT_FDCWD ,
then
pathname
is interpreted relative to the current working
directory of the calling process (like
utimes(2)).
If
R pathname
is absolute, then
dirfd
is ignored.
RETURN VALUE
On success,
R 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
R futimesat ().
The following additional errors can occur for
R 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
R futimesat ()
was added to Linux in kernel 2.6.16.
CONFORMING TO
This system call is non-standard but is proposed
for inclusion in a future revision of POSIX.1.
A similar system call exists on Solaris.
NOTES
Glibc Notes
If
pathname
is NULL, then the glibc
R futimesat ()
wrapper function updates the times for the file referred to by
R dirfd .
