使用纯C ++进行文件映射 [英] file mapping using pure c++

问题描述

我可以实现一种类似于"Windows文件映射"的机制，在其中可以将磁盘上的大文件当作未加载的文件来对待吗?

can I implement a mechanism like "windows file mapping" in which you can treat large files on disk as if they''re already loaded while they''re not?

推荐答案

您是指内存映射文件吗?如果是这样，请参见 http://msdn.microsoft.com/en-us/library/dd997372.aspx [ ^ ]

如果您是直接访问磁盘，则可以使用CreateFile 来完成.不过，您可能会在Vista/Windows 7上遇到访问限制.

Do you mean memory mapped files? If so, see http://msdn.microsoft.com/en-us/library/dd997372.aspx[^]

If you mean direct disk access, you can use CreateFile to do that. You may run into access restrictions on Vista/Windows 7 though.

ACE是高效的，并且经过了严格的测试:)

它也可用于大多数相关的操作系统和编译器...

Have a look at the ACE C++ library[^]:

ACE is efficient and exceptionally well tested :)

It''s also available for most relevant operating systems and compilers ...
