| Abstract: | First, this paper introduces the memory management mode and inter-process communication mode in Windows operating system, and then introduees the definition of memory-mapped file, the prineiple of using it to share memory between proeesses, as well as its operation method and proeedure. Finally, aeeording to the theory of memory-mapped file sharing data between proeesses, the message queue sharing data transmission between proeesses is realized and applied in the engineering praetiee, whieh is quite effeetive. |

| Keywords: | inter-proeess data transmission memory-mapped file virtual address spaee message queue |
