   8  * Those  bt_bt2_*() functions below ensure that when the API function
   9  * fails, the output parameter is set to `NULL`.  This is necessary
  10  * because the epilogue of the `something **OUT` typemap will use that
  11  * value to make a Python object.  We can't rely on the initial value of
  12  * `*OUT`; it could point to unreadable memory.
