NAME¶
chdir, fchdir - change working directorySYNOPSIS¶
#include <unistd.h>Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_BSD_SOURCE ||
_XOPEN_SOURCE >= 500 ||
_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
|| /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
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.
- EACCES
- Search permission was denied on the directory open on fd.
- EBADF
- fd is not a valid file descriptor.
