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.
