  22.      The _pppp_rrrr_oooo_cccc______ssss_iiii_gggg_nnnn_aaaa_llll function can be used to post a signal to the process
  23.      represented by _p_r_e_f.  This will interrupt any process blocked in
  24.      _SSSS_VVVV______WWWW_AAAA_IIII_TTTT______SSSS_IIII_GGGG(D3) or _SSSS_LLLL_EEEE_EEEE_PPPP______LLLL_OOOO_CCCC_KKKK______SSSS_IIII_GGGG(D3) at the time the signal is posted,
  25.      causing those functions to return prematurely in most cases.  If the
  26.      process has exited then this function has no effect.

  28.    RRRReeeettttuuuurrrrnnnn VVVVaaaalllluuuueeeessss
  29.      If the process still exists, 0 is returned.  Otherwise, -1 is returned to
  30.      indicate that the process no longer exists.

  33.      Valid signal numbers are listed in _ssss_iiii_gggg_nnnn_aaaa_llll_ssss(D5).
  34.  
  35.      STREAMS drivers and modules should not use this mechanism for signaling
  36.      processes.  Instead, they can send _MMMM______SSSS_IIII_GGGG or _MMMM______PPPP_CCCC_SSSS_IIII_GGGG STREAMS messages to
  37.      the stream head.
  38.  
  39.      _pppp_rrrr_oooo_cccc______ssss_iiii_gggg_nnnn_aaaa_llll must not be used to send _SSSS_IIII_GGGG_TTTT_SSSS_TTTT_PPPP to a process.
