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.
