Because each process (and the kernel) can have identical addresses that refer to different regions of physical memory, it's not immediately possible to share memory.
因为每个进程(和内核)会有相同地址指向不同的物理内存区域,不可能立即共享内存。
My dear friends, can you share your earliest memory with us?
亲爱的朋友,我们分享下最早的记忆吧。
Do not communicate by sharing memory; instead, share memory by communicating.
不要通过共享内存来通信,相反,通过通信来共享内存。
