  15.      When a process waits for status from its children via either the _wwww_aaaa_iiii_tttt or
  16.      _wwww_aaaa_iiii_tttt_pppp_iiii_dddd function, the status returned may be evaluated with the following
  17.      macros, defined in _ssss_yyyy_ssss_////_wwww_aaaa_iiii_tttt_...._hhhh.  These macros evaluate to integral
  18.      expressions.  The _s_t_a_t argument to these macros is the integer value
  19.      returned from _wwww_aaaa_iiii_tttt or _wwww_aaaa_iiii_tttt_pppp_iiii_dddd.
  20.  
  21.      _WWWW_IIII_FFFF_EEEE_XXXX_IIII_TTTT_EEEE_DDDD_((((_s_t_a_t_))))     Evaluates to a non-zero value if status was returned
  22.                          for a child process that terminated normally.
  23.  
  24.      _WWWW_EEEE_XXXX_IIII_TTTT_SSSS_TTTT_AAAA_TTTT_UUUU_SSSS_((((_s_t_a_t_))))   If the value of _WWWW_IIII_FFFF_EEEE_XXXX_IIII_TTTT_EEEE_DDDD_((((_s_t_a_t_)))) is non-zero, this
  25.                          macro evaluates to the exit code that the child
  26.                          process passed to ______eeee_xxxx_iiii_tttt or _eeee_xxxx_iiii_tttt, or the value that
  27.                          the child process returned from _mmmm_aaaa_iiii_nnnn.
  28.  
  29.      _WWWW_IIII_FFFF_SSSS_IIII_GGGG_NNNN_AAAA_LLLL_EEEE_DDDD_((((_s_t_a_t_))))   Evaluates to a non-zero value if status was returned
  30.                          for a child process that terminated due to the
  31.                          receipt of a signal.
  32.  
  33.      _WWWW_TTTT_EEEE_RRRR_MMMM_SSSS_IIII_GGGG_((((_s_t_a_t_))))      If the value of _WWWW_IIII_FFFF_SSSS_IIII_GGGG_NNNN_AAAA_LLLL_EEEE_DDDD_((((_s_t_a_t_)))) is non-zero, this
  34.                          macro evaluates to the number of the signal that
  35.                          caused the termination of the child process.
  36.  
  37.      _WWWW_IIII_FFFF_SSSS_TTTT_OOOO_PPPP_PPPP_EEEE_DDDD_((((_s_t_a_t_))))    Evaluates to a non-zero value if status was returned
  38.                          for a child process that is currently stopped.
  39.  
  40.      _WWWW_SSSS_TTTT_OOOO_PPPP_SSSS_IIII_GGGG_((((_s_t_a_t_))))      If the value of _WWWW_IIII_FFFF_SSSS_TTTT_OOOO_PPPP_PPPP_EEEE_DDDD_((((_s_t_a_t_)))) is non-zero, this
  41.                          macro evaluates to the number of the signal that
  42.                          caused the child process to stop.
  43.  
  44.      _WWWW_IIII_FFFF_CCCC_OOOO_NNNN_TTTT_IIII_NNNN_UUUU_EEEE_DDDD_((((_s_t_a_t_))))  Evaluates to a non-zero value if status was returned
  45.                          for a child process that has continued.
  46.  
  47.      _WWWW_CCCC_OOOO_RRRR_EEEE_DDDD_UUUU_MMMM_PPPP(_s_t_a_t_))))     If the value of _WWWW_IIII_FFFF_SSSS_IIII_GGGG_NNNN_AAAA_LLLL_EEEE_DDDD_((((_s_t_a_t_)))) is non-zero, this
  48.                          macro evaluates to a non-zero value if a core image
  49.                          of the terminated child was created.
