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. | |
