如何在 Linux 上的 Common Lisp 中 memory map 文件？

Question

How can I achieve memory mapping in Common Lisp either through cffi or a custom library?

There is void *mmap(void *addr, size_t length, int prot, int flags, int fd, off_t offset); in C language.

Answer 1

There is already How do I memory map tmpfs files in sbcl? , but nowadays there is a portable library for that: just (ql:quickload "mmap") .

The repository is here .

Answer 2

Some implementations let you specify in a call to function open take the file should be memory-mapped. At least Allegro CL supports (open.. :mapped t) . This also works in macro with-open-file which expands into open .
