You can even create a shared memory mapped file for sharing data between processes on Windows in pure Python. It's not really obvious from the mmap description, but calling shmem = mmap.mmap(0, 32000, "spam") creates (or opens, if it already exists) a shared memory block, not based an any existing file. In other words, the fileno (first parameters) must be 0, and the last one specifies the system wide name of the shared memory block. Thomas -- http://mail.python.org/mailman/listinfo/python-list
