or the interface may not be implemented on Linux.
NAME
fchdir
--- change working directory
SYNOPSIS
#include <unistd.h>
int fchdir(int fildes);
DESCRIPTION
The
fchdir()
function shall be equivalent to
chdir()
except that the directory that is to be the new current working
directory is specified by the file descriptor
fildes.
A conforming application can obtain a file descriptor for a file of
type directory using
open(),
provided that the file status flags and access modes do not contain
O_WRONLY or O_RDWR.
RETURN VALUE
Upon successful completion,
fchdir()
shall return 0. Otherwise, it shall return -1 and set
errno
to indicate the error. On failure the current working directory
shall remain unchanged.
ERRORS
The
fchdir()
function shall fail if:
- EACCES
-
Search permission is denied for the directory referenced by
fildes.
- EBADF
-
The
fildes
argument is not an open file descriptor.
- ENOTDIR
-
The open file descriptor
fildes
does not refer to a directory.
The
fchdir()
may fail if:
- EINTR
-
A signal was caught during the execution of
fchdir().
- EIO
-
An I/O error occurred while reading from or writing to the file system.
