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