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 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.
