11 int chdir(const char *path);
12 int fchdir(int fd);
13
14 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
15
16 fchdir():
17 _XOPEN_SOURCE >= 500
18 || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
19 || /* Glibc up to and including 2.19: */ _BSD_SOURCE

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
29 On success, zero is returned. On error, -1 is returned, and errno is
30 set appropriately.
31
33 Depending on the filesystem, 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 directory specified in path 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.
60
62 POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD.
63
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).
