  24.      _UUUU_NNNN_LLLL_OOOO_CCCC_KKKK releases the basic lock specified by _l_o_c_k_p and then sets the

  31.      See the description of the _m_i_n__p_l argument to _LLLL_OOOO_CCCC_KKKK______AAAA_LLLL_LLLL_OOOO_CCCC(D3) for a list
  32.      of the valid values for _p_l.  If lock calls are not being nested or if the
  33.      caller is unlocking in the reverse order that locks were acquired, the _p_l
  34.      argument should be the value that was returned from the corresponding
  35.      call to acquire the lock.  The caller may need to specify a different
  36.      returned value by other _LLLL_OOOO_CCCC_KKKK for _p_l if nested locks are released in some
  37.      order other than the reverse order of acquisition, so as to ensure that
  38.      the interrupt priority level is kept sufficiently high to block interrupt
  39.      code that might attempt to acquire locks which are still held.
