The POSIX 2024 standard has been released with various improvements and removals compared to the previous version. Sortix, an operating system, has already implemented most of the new interfaces, with some still pending. Users can try out the latest Sortix nightly build to experience the new features. The changes include new functions like _Fork(), accept4(), aligned_alloc(), asprintf(), dladdr(), dup3(), and more. Some functions like posix_close() and posix_devctl() will not be implemented in Sortix due to complexity or being optional. The implementation status of each function is detailed, including whether it has been implemented, postponed, or rejected. Sortix aims to provide a comprehensive implementation of the POSIX 2024 standard, ensuring compatibility and functionality for users.
