Section: Linux Programmer's Manual (2)
Updated: 2010-09-20
NAME
chdir, fchdir - change working directory
SYNOPSIS
#include <unistd.h>
int chdir(const char *path);
int fchdir(int fd);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
fchdir():
-
- Since glibc 2.12:
-
_BSD_SOURCE || _XOPEN_SOURCE >= 500 ||
_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED ||
_POSIX_C_SOURCE >= 200809L
- Before glibc 2.12:
-
_BSD_SOURCE || _XOPEN_SOURCE >= 500
_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
DESCRIPTION
chdir()
changes the current working directory of the calling process to the
directory specified in
path.
fchdir()
is identical to
chdir();
the only difference is that the directory is given as an
open file descriptor.
RETURN VALUE
On success, zero is returned.
On error, -1 is returned, and
errno
is set appropriately.
ERRORS
Depending on the file system, other errors can be returned.
The more
general errors for
chdir()
are listed below:
- EACCES
-
Search permission is denied for one of the components of
path.
(See also
path_resolution(7).)
- EFAULT
-
path
points outside your accessible address space.
- EIO
-
An I/O error occurred.
- ELOOP
-
Too many symbolic links were encountered in resolving
path.
- ENAMETOOLONG
-
path
is too long.
- ENOENT
-
The file does not exist.
- ENOMEM
-
Insufficient kernel memory was available.
- ENOTDIR
-
A component of
path
is not a directory.
The general errors for
fchdir()
are listed below:
- EACCES
-
Search permission was denied on the directory open on
fd.
- EBADF
-
fd
is not a valid file descriptor.
CONFORMING TO
SVr4, 4.4BSD, POSIX.1-2001.
NOTES
The current working directory is the starting point for interpreting
relative pathnames (those not starting with '/').
A child process created via
fork(2)
inherits its parent's current working directory.
The current working directory is left unchanged by
execve(2).
The prototype for
fchdir()
is only available if
_BSD_SOURCE
is defined, or
_XOPEN_SOURCE
is defined with the value 500.
