It's even more fun when you're mixing libraries, and some of them return 1 on success, some of them return zero, and some -1, and you can't tell by inspection which is which. Bonus points if the API you're using inconsistently mixes boolean, null-pointer, HRESULT, DWORD, and returning a status in a value you pass a pointer to (you did initialize that value, right?) Why do we keep doing this to ourselves?
