- _D_i_r_n_a_m_e is the address of the pathname of a directory, terminated by an
- ASCII NUL. CChhrroooott() causes _d_i_r_n_a_m_e to become the root directory, that
- is, the starting point for path searches of pathnames beginning with `/'.
-
- In order for a directory to become the root directory a process must have
- execute (search) access for that directory.
-
- It should be noted that cchhrroooott() has no effect on the process's current
- directory.
-
- This call is restricted to the super-user.

- Upon successful completion, a value of 0 is returned. Otherwise, a value
- of -1 is returned and _e_r_r_n_o is set to indicate an error.

- CChhrroooott() will fail and the root directory will be unchanged if:
-
- [ENOTDIR] A component of the path name is not a directory.
-
- [ENAMETOOLONG]
- A component of a pathname exceeded {NAME_MAX} characters,
- or an entire path name exceeded {PATH_MAX} characters.
-
- [ENOENT] The named directory does not exist.
-
- [EACCES] Search permission is denied for any component of the path
- name.
-
- [ELOOP] Too many symbolic links were encountered in translating the
- pathname.
-
- [EFAULT] _P_a_t_h points outside the process's allocated address space.
-
- [EIO] An I/O error occurred while reading from or writing to the
- file system.
