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.
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
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_res-
EFAULT path points outside your accessible address space.
EIO An I/O error occurred.
ELOOP Too many symbolic links were encountered in resolving path.
path is too long.
ENOENT The file does not exist.
ENOMEM Insufficient kernel memory was available.
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.

The current working directory is the starting point for interpreting relative pathnames
(those not starting with '/').
A child process created via fork(2) inherits its parent's current working directory. The
current working directory is left unchanged by execve(2).
