- _S_i_g_s_e_t_m_a_s_k sets the current signal mask (those signals that
- are blocked from delivery). Signals are blocked if the
- corresponding bit in _m_a_s_k is a 1; the macro _s_i_g_m_a_s_k is pro-
- vided to construct the mask for a given _s_i_g_n_u_m.
-
- The system quietly disallows SIGKILL, SIGSTOP, or SIGCONT to
- be blocked.
