  21.      _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT is a debugging interface for verifying program invariants within
  22.      code that is compiled with the _DDDD_EEEE_BBBB_UUUU_GGGG compilation option defined.

  25.      If _e_x_p_r_e_s_s_i_o_n evaluates to non-zero, _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT returns no value.  If
  26.      _e_x_p_r_e_s_s_i_o_n evaluates to zero, _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT panics the system.

  29.      _e_x_p_r_e_s_s_i_o_n is a boolean expression that the caller expects to evaluate to
  30.      non-zero (that is, the caller is asserting that the expression has a
  31.      non-zero value).  If _e_x_p_r_e_s_s_i_o_n evaluates to non-zero, the _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT call
  32.      has no effect.  If _e_x_p_r_e_s_s_i_o_n evaluates to zero, _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT causes the system
  33.      to panic with the following message:
  34.      _PPPP_AAAA_NNNN_IIII_CCCC_:::: _aaaa_ssss_ssss_eeee_rrrr_tttt_iiii_oooo_nnnn _ffff_aaaa_iiii_llll_eeee_dddd_:::: _e_x_p_r_e_s_s_i_o_n_,,,, _ffff_iiii_llll_eeee_:::: _f_i_l_e_n_a_m_e_,,,, _llll_iiii_nnnn_eeee_:::: _l_i_n_e_n_o
  35.  
  36.      where _f_i_l_e_n_a_m_e is the name of the source file in which the failed
  37.      assertion appears and _l_i_n_e_n_o is the line number of the _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT call within
  38.      the file.
  39.  
  40.      When the _DDDD_EEEE_BBBB_UUUU_GGGG compilation option is not defined, _AAAA_SSSS_SSSS_EEEE_RRRR_TTTT calls are not
  41.      compiled into the code, and therefore have no effect, including the fact
  42.      that _e_x_p_r_e_s_s_i_o_n is not evaluated.
