  30.      _s_i_g_s_e_t_m_a_s_k sets the current signal mask (those signals that are blocked
  31.      from delivery).  Signals are blocked if the corresponding bit in _m_a_s_k is
  32.      a 1 (numbering the bits from 1 to 32); the macro _s_i_g_m_a_s_k is provided to
  33.      construct the mask for a given _s_i_g_n_u_m.

  44.      The 4.3BSD and System V signal facilities have different semantics.
