This article is to share with you about the example analysis of Redox OS, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Redox OS is a general-purpose operating system written almost entirely in the Rust language and its surrounding ecology (such as file systems, display servers, and Rust versions of libc). It follows the microkernel architecture and is compatible with POSIX to some extent.

The project released version 0.5 of Redox a few days ago. It has been one year and four days since the last release of Redox OS. In the meantime, the Redox team has been working to improve the Redox ecosystem. Most of the effort is focused on relibc, a new C library written in Rust and maintained by the Redox OS project; in addition, cookbook has added new software packages. Now, relibc is more powerful than the C library newlib that Redox used to rely on. Many important libraries and programs have been added to this version.

At first glance, this version of the ISO image is no different from the last released version 0.3.5-with the same login screen and the same default background and application. But this is an achievement in itself. Because the work on relibc is so intensive that it touches almost every part of the system.

Once you understand it in depth, you will find that the change is obvious. The event system has been redesigned to provide correct support for select and poll, and complete memory mapping support. Pthreads is implemented, as well as some signal-related system calls. All of these changes provide better support for LLVM.

The above is the example analysis of Redox OS, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
