But that defeats the purpose of zero copy, because a copy is generated by the tobytes() method. So the next thing to try was to "cast" the memoryview to a bytearray. In other words, create a bytearray that uses the memory view "mv" as its backing data. I thought that this would be simple, but I cannot figure out how to do this. Does anyone out there know how?
