I was wondering how can I make the IO faster by writing and reading temporary files to main memory. I've used to write to /dev/shm in Linux.

But now I'm in Windows 7. Anyone knows the answer ?

Thanks

If I understood it correctly (based on this post) what you are looking for is Memory Mapped Files.

    I'm not sure why this is the accepted answer as the question was about an equivalence of `/dev/shm` for Windows (or at least that was my interpretation). Is there shared ram based filesystem for Windows? – BrendanSimon Sep 12 '20 at 08:22

You can use CreateFile() with FILE_ATTRIBUTE_TEMPORARY, and Windows should try to keep it in cache as much as possible.

    What I wanted is a nonprogramming way. Just like writing regular files in specific directory. – ablimit Jun 11 '10 at 01:05
