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

PROLOG         top

       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         top

       fchdir — change working directory

SYNOPSIS         top

       #include <unistd.h>

       int fchdir(int fildes);

DESCRIPTION         top

       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         top

       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         top

       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.
