Coming up we'll look at memory mapping, how file reading and writing ties into all this and what memory usage figures mean.
进而我们会看看内存映射原理、与之相关的文件读写机制以及内存使用情况图表所揭示的含义。
Even though the data segment maps a file, it is a private memory mapping, which means that updates to memory are not reflected in the underlying file.
尽管数据段映射了文件,但这种内存映射是私有的,也就是说,数据段的内存更新不会在其映射的文件中生效。
The memory mapping feature enables you to display a region of memory according to a layout defined in an XML file.
内存映射特性能够使您根据XML文件中所定义的布局来显示内存的某个区域。
msync(): Used to synchronize a shared memory segment with the file system—a technique useful when mapping a file into memory.
msync():用来让共享内存段与文件系统同步 —当把文件映射到内存时,这种技术有用。
Memory mapping is a convenient and high-performance way to do file I/O, so it is used for loading dynamic libraries.
执行文件I /O,内存映射是一个方便的和高性能的方式,因此,它被用于加载动态库。
Even though the data segment maps a file, it is a private memory mapping, which means that updates to memory are not reflected in the underlying file.
尽管数据段映射了一个文件,它是一个私有内存映射,这意味着更新到内存中不反映在底层的文件。
Memory mapping is used to map image and data files into a processes address space. In memory mapping, the contents of a file are linked directly into the virtual address space of a process.
内存映射被用于将映像和数据文件映射到一个进程的虚拟地址空间中,也就是将文件内容直接地连接到虚地址中。
File mapping and memory mapping view.
文件的映射和内存映射视图。
You can supply a handle to a file-mapping object that the function will use to create the bitmap, or you can let the system allocate the memory for the bitmap.
可传一个文件映射对象的句柄来创始位图。或者让系统为位图分配内存。
