Name
futimesat — change timestamps of a file relative to
a directory file descriptor
Synopsis
int
futimesat( |
int |
dirfd, |
| |
const char * |
pathname, |
| |
const struct timeval
|
times); |
DESCRIPTION
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 futimesat(). 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 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 futimesat() wrapper function updates the
times for the file referred to by dirfd.
