DESCRIPTION
     The ck_pr_dec(3) family of functions atomically decrement the value pointed
     to by target.

RETURN VALUES
     The ck_pr_dec_zero family of functions set the value pointed  to  by  z  to
     true  if  the  result  of the decrement operation was 0. They set the value
     pointed to by z to false otherwise.  The ck_pr_dec_is_zero family of  func-
     tion  return  true if the result of the decrement operation was 0 and false
     otherwise.
