Do C function pointer callbacks with pointer parameters always have the parameters mapped as CPointer rather that CValuesRef?
Is this because they are called directly rather than through a KLib wrapper? Does this mean if passing in strings you have to allocate and free (or use getPointer within a memScoped)?

Hello! If I understand it correctly, the answer is “yes”. But, why don’t you use .cstr/.toKString conversions? I’m not sure that manual allocation is needed here.

The signature of the function is CPointer rather than CPointed so the .cstr won’t work on it’s own (it returns CValues). So I have to call .cstr.getPointer(memScope) to allocate it.
