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 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.

CONFORMING TO
