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.
