Is there a way in Swift 3 to pass a null pointer to a C function that
takes an implicitly unwrapped unsafe pointer? I understand that
pointer parameters in C that don't specify nullability are mapped to
implicitly unwrapped pointers in Swift 3. Since it's not uncommon for
existing unannotated C APIs to accept null pointers, I assume there
has to be a way other than creating my own bridge functions in C. I
hope I am not wrong.
I am a bit surprised that I couldn't find an answer to this, neither
on this list nor on stackoverflow, as I presume I am not the only one
with this problem. Sorry, if I missed something.
