- _G_e_t_h_o_s_t_n_a_m_e returns the standard host name for the current
- processor, as previously set by _s_e_t_h_o_s_t_n_a_m_e. The parameter
- _n_a_m_e_l_e_n specifies the size of the _n_a_m_e array. The returned
- name is null-terminated unless insufficient space is pro-
- vided.
-
- _S_e_t_h_o_s_t_n_a_m_e sets the name of the host machine to be _n_a_m_e,
- which has length _n_a_m_e_l_e_n. This call is restricted to the
- super-user and is normally used only when the system is
- bootstrapped.
