FCHDIR(3P)		   POSIX Programmer's Manual		    FCHDIR(3P)

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.
