Would you mind to give examples? I'm not sure how to use this API.

I understood that PyErr_WriteUnraisable(obj) can be written as:

PyErr_FormatUnraisable("Exception ignored in: %R", obj);

And without an exception an object, it should be:

PyErr_FormatUnraisable("Exception ignored in:");

Do the format must end with a newline character?

If format is NULL, only the traceback is printed.

What's the usage of this mode? Is the caller expected to log something like "Exception ignored in xxx" manually?
