CHDIR(2) Linux Programmer s Manual CHDIR(2)

NAME chdir, fchdir - change working directory

SYNOPSIS #include <unistd.h>

int chdir(const char *path); int fchdir(int fd);

DESCRIPTION chdir() changes the current working directory to that 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 directories in the path prefix of path. (See also path_resolution(2).)

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.

NOTES A child process created via fork(2) inherits its parents current work- ing 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.

CONFORMING TO SVr4, 4.4BSD, POSIX.1-2001.
