Could not use multiprocessing.shared_memory in PyPy 3.8

I want to run the Python code using multiple CPU cores. I use multiprocessing.shared_memory to transmit data to the cores. But it seems multiprocessing.shared_memory is not supported in PyPy 3.8. I run the attached file, and get an error "AttributeError: module '_winapi' has no attribute 'CreateFileMapping'". Will the multiprocessing.shared_memory be support in the coming version of PyPy? Or my operation is somewhere wrong?
