-.SH DESCRIPTION
-The
-.BR fstatat ()
-system call operates in exactly the same way as
-.BR stat (2),
-except for the differences described in this manual page.
-
-If the pathname given in
-.I pathname
-is relative, then it is interpreted relative to the directory
-referred to by the file descriptor
-.I dirfd
-(rather than relative to the current working directory of
-the calling process, as is done by
-.BR stat (2)
-for a relative pathname).
-
-If
-.I pathname
-is relative and
-.I dirfd
-is the special value
-.BR AT_FDCWD ,
-then
-.I pathname
-is interpreted relative to the current working
-directory of the calling process (like
-.BR stat (2)).
-
-If
-.I pathname
-is absolute, then
-.I dirfd
-is ignored.
-
-.I flags
-can either be 0, or include one or more of the following flags ORed:
-.TP
-.BR AT_EMPTY_PATH " (since Linux 2.6.39)"
-.\" commit 65cfc6722361570bfe255698d9cd4dccaf47570d
-If
-.I pathname
-is an empty string, operate on the file referred to by
-.IR dirfd
-(which may have been obtained using the
-.BR open (2)
-.B O_PATH
-flag).
-In this case,
-.I dirfd
-can refer to any type of file, not just a directory.
-
-.TP
-.BR AT_NO_AUTOMOUNT " (since Linux 2.6.38)"
-Don't automount the terminal ("basename") component of
-.I pathname
-if it is a directory that is an automount point.
-This allows the caller to gather attributes of an automount point
-(rather than the location it would mount).
-This flag can be used in tools that scan directories
-to prevent mass-automounting of a directory of automount points.
-The
-.B AT_NO_AUTOMOUNT
-flag has no effect if the mount point has already been mounted over.
-.TP
-.B AT_SYMLINK_NOFOLLOW
-If
-.I pathname
-is a symbolic link, do not dereference it:
-instead return information about the link itself, like
-.BR lstat (2).
-(By default,
-.BR fstatat ()
-dereferences symbolic links, like
-.BR stat (2).)
-.SH RETURN VALUE
-On success,
-.BR fstatat ()
-returns 0.
-On error, \-1 is returned and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-The same errors that occur for
-.BR stat (2)
-can also occur for
-.BR fstatat ().
-The following additional errors can occur for
-.BR fstatat ():
-.TP
-.B EBADF
-.I dirfd
-is not a valid file descriptor.
-.TP
-.B EINVAL
-Invalid flag specified in
-.IR flags .
-.TP
-.B ENOTDIR
-.I pathname
-is relative and
-.I dirfd
-is a file descriptor referring to a file other than a directory.
-.SH VERSIONS
-.BR fstatat ()
-was added to Linux in kernel 2.6.16;
-library support was added to glibc in version 2.4.
-.SH CONFORMING TO
-POSIX.1-2008.
-A similar system call exists on Solaris.
-.SH NOTES
-See
-.BR openat (2)
-for an explanation of the need for
-.BR fstatat ().
-
-The underlying system call employed by the glibc
-.BR fstatat ()
-wrapper function is actually called
-.BR fstatat64 ().
