Linux是否相当于VirtualProtectEx? [英] Linux equivalent for VirtualProtectEx?

问题描述

我正在做一些简单的JITing，并使用 VirtualProtectEx 在Windows下将页面标记为可执行文件. 与Linux，最好还有其他类似POSIX/Unix的操作系统下的操作系统等效吗?

I am doing some simple JITing, and use VirtualProtectEx under Windows to mark pages as executable. What would be the equivalent of that under Linux, and preferably, other POSIX/Unix-like OSes too?

推荐答案

您正在寻找 mprotect ，也可能是 mmap .请注意，与Windows不同，进程A无法更改进程B的内存映射(缺少

You are looking for mprotect and probably also mmap. Note that, unlike with Windows, there is no way for process A to change process B's memory map (short of horrible tricks with ptrace).
