  20      SIGSEGV_EXC_STATE_TYPE
  21           is a type containing state describing details of an exception,
  22           excluding the thread state.
  23      SIGSEGV_EXC_STATE_FLAVOR
  24           is a macro expanding to a constant int value denoting the
  25           SIGSEGV_EXC_STATE_TYPE type.
  26      SIGSEGV_EXC_STATE_COUNT
  27           is a macro expanding to the number of words of the
  28           SIGSEGV_EXC_STATE_TYPE type.
  29
  30      SIGSEGV_THREAD_STATE_TYPE
  31           is a type containing the state of a (stopped or interrupted) thread.
  32      SIGSEGV_THREAD_STATE_FLAVOR
  33           is a macro expanding to a constant int value denoting the
  34           SIGSEGV_THREAD_STATE_TYPE type.
  35      SIGSEGV_THREAD_STATE_COUNT
  36           is a macro expanding to the number of words of the
  37           SIGSEGV_THREAD_STATE_TYPE type.
  38
  39      SIGSEGV_FAULT_ADDRESS(thr_state, exc_state)
  40           is a macro for fetching the fault address.
  41
  42      SIGSEGV_STACK_POINTER(thr_state)
  43           is a macro, expanding to an lvalue, for fetching the stackpointer at
  44           the moment the fault occurred, and for setting the stackpointer in
  45           effect when the thread continues.
  46
  47      SIGSEGV_PROGRAM_COUNTER(thr_state)
  48           is a macro, expanding to an lvalue, for fetching the program counter
  49           (= instruction pointer) at the moment the fault occurred, and for
  50           setting the program counter before letting the thread continue.
