Hi,
In plain C (not C++), void* pointer means "anything goes", it's like a placeholder that accepts any data. malloc won't break, it just returns a void* pointer, it doesn't care what are you using it for. Remember that C and C++ are unmanaged languages so memory management is up to the app developer. What's important is that you declare framebuffer with a datatype that is meaningful for the kind of access/arithmetic you're going to perform on it. Tilengine doesn't care as long as it encodes a 32-bit ARGB pixel format.
C++ is more strict with pointer matching than C, and different types must be cast explicitly. So if you're declaring framebuffer with a different datatype than uint8_t*, you must cast it:
Regards,
