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 dif-
       fer (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.
