内存映射文件:与虚拟内存一样,内存映射文件可以用来保留一个地址空间的区域,并将物理存储器提交给该区域。它们之间的差别是,物理存储器来自一个已经位于磁盘上的文件,而不是系统的页文件。一旦该文件被映射,就可以访问它,就像整个文件已经加载内存一样-Memory-mapped file: same as virtual memory, memory mapped files can be used to reserve an address space of the region, and submitted to the area of physical memory. The difference between them is already in physical memory from a file on disk, rather than the system page file. Once the file is mapped, you can access it, like memory, like the entire file has been loaded
