The async_mmap feature has several advantages: Richer expressiveness and more flexible memory access pattern. The mmap () function shall establish a mapping between a process&#39; address space and a file, shared memory object, or typed memory object. Updates to the mapping are visible to other processes that map this file, and are carried through to the underlying file. As for whether any system actually will perform async readahead under any circumstances, I am. DESCRIPTION top mmap () creates a new mapping in the virtual address space of the calling process. The starting address for the new mapping is specified in addr. In this way, users have maximal control over how they want to access the external memory.<\/strong><\/p>\n<p><figure> \t\t<img decoding=\"async\" src=\"https:\/\/luck.rain7.top\/images\/2020\/04\/22\/Async-map.png\" alt=\"\u5982\u4f55\u6b63\u786e\u7684\u5728 Array.map \u4f7f\u7528 async - \u9707\u96e8\u7684\u4e2a\u4eba\u7f51\u7ad9\" style=\"width: 100%; padding: 5px; background-color: grey;\"><figcaption>\u5982\u4f55\u6b63\u786e\u7684\u5728 Array.map \u4f7f\u7528 async &#8211; \u9707\u96e8\u7684\u4e2a\u4eba\u7f51\u7ad9 (Cole Guzman)<\/figcaption><\/figure>\n<p> \t \t<strong>Mmap Async<\/strong>. <strong>A new reference for the file specified by filedes is created, which is not removed by closing the file. address gives a preferred starting address for the mapping..
