fstatat — get file status relative to a directory file descriptor
#define _ATFILE_SOURCE #include <sys/stat.h>
int
fstatat( |
int | dirfd, |
const char * | pathname, | |
struct stat * | buf, | |
int | flags) ; |
The fstatat
() system call
operates in exactly the same way as stat(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 stat(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 stat(2)).
If pathname
is
absolute, then dirfd
is ignored.
flags
can either
be 0, or include the following flag:
On success, fstatat
()
returns 0. On error, −1 is returned and errno
is set to indicate the error.
The same errors that occur for stat(2) can also occur for
fstatat
(). The following
additional errors can occur for fstatat
():
dirfd
is not
a valid file descriptor.
Invalid flag specified in flags
.
pathname
is
relative and dirfd
is a file
descriptor referring to a file other than a
directory.
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.
