     _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 or SIGSTOP to be
     blocked.

RREETTUURRNN VVAALLUUEE
     The previous set of masked signals is returned.
