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 cur-
       rent 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.
