Windows中是否有任何内存虚拟文件API？

Question

I have a module load a file by its path, However I find it is slow. I want to accelerate it, Is there any technology in Windows to create a virtual memory file for the module?

Many thanks

Answer 1

I tested BoxedApp SDK .

It is awesome, but it is not free :)

Answer 2

我不完全知道你是问什么的，但如果你只是想创建一个将生活在RAM（如果可能）的临时文件，可以使用CreateFile与FILE_ATTRIBUTE_TEMPORARY 。

Answer 3

Assuming you're talking about memory mapped file, yes there are APIs for that. It's too much to discuss in a little SO answer, and besides it's many many years since I used so I don't even recall the function names. Here's how I found info on that quickly: http://www.google.com/search?q=memory+mapped+file+windows .

However, other simpler means are probably the answer to "I find it is slow".

There can be many different reasons for slowness. Please post some code. Then better answers can be given.

Cheer & hth.,
