PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       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.
