NAME

SYNOPSIS

9       #include <unistd.h>
10
11       int chdir(const char *path);
12       int fchdir(int fd);

14   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
15
16       fchdir():
17           _BSD_SOURCE || _XOPEN_SOURCE >= 500 ||
18           _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
19           || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L

DESCRIPTION

22       chdir() changes the current working directory of the calling process to
23       the directory specified in path.
24
25       fchdir()  is  identical  to  chdir();  the  only difference is that the
26       directory is given as an open file descriptor.
27

RETURN VALUE

29       On success, zero is returned.  On error, -1 is returned, and  errno  is
30       set appropriately.
31

ERRORS

33       Depending  on  the file system, other errors can be returned.  The more
34       general errors for chdir() are listed below:
35
36       EACCES Search permission is denied for one of the components  of  path.
37              (See also path_resolution(7).)
38
39       EFAULT path points outside your accessible address space.
40
41       EIO    An I/O error occurred.
42
43       ELOOP  Too many symbolic links were encountered in resolving path.
44
45       ENAMETOOLONG
46              path is too long.
47
48       ENOENT The file does not exist.
49
50       ENOMEM Insufficient kernel memory was available.
51
52       ENOTDIR
53              A component of path is not a directory.
54
55       The general errors for fchdir() are listed below:
56
57       EACCES Search permission was denied on the directory open on fd.
58
59       EBADF  fd is not a valid file descriptor.

CONFORMING TO

62       SVr4, 4.4BSD, POSIX.1-2001.
63

NOTES

65       The  current  working  directory is the starting point for interpreting
66       relative pathnames (those not starting with '/').
67
68       A child process created via fork(2) inherits its parent's current work‐
69       ing  directory.   The  current  working  directory is left unchanged by
70       execve(2).
