Author here. Sortix is Sortix. MINIX is MINIX. I think each project has different goals and that's fair. Some thoughts though, for my os-test project I went and installed every free software Unix-like OS and ran a lot of tests on each

Yep. I already have an issue about virtio filed at < https://gitlab.com/sortix/sortix/issues/473> . Not too high priority to implement but something I'd love to get to. Feel free to post additional h

Author here. Like in Linux, libc provides errno on Sortix. The difference is that glibc does "#define errno (*__get_errno_location())" while Sortix libc does "__thread int errno;". linux syscalls return a negative value

Author here. POSIX requires errno to be thread local, but with few requirements. Commonly libc's #define errno (*__get_errno_location()). Why? It's because the thread local storage isn't online very early on. The libc literal

Author here. I'll probably omit the word 'modern' in the next release. Not for the reasons listed here, but because a bunch of stuff purports to be modern while forgetting the lessons of the past. I implement POSIX not for th

Author here. Yep, I don't want to force a particular bootloader on anyone. The bootloader is a piece of software owned by the system administrator, not necessarily by any of the several operating systems installed side by side. If I fo

Thanks! Be sure to let me know what you think.

I used to start new coding projects weekly to play with one thing or another, not getting anywhere. With Sortix, there's now so many interesting areas to work on that I can work on whatever I fancy, and then still slowly accumulate use

Thanks! You shouldn't, but it could be an addition if you want something to tinker with. I've been dogfooding with it, for instance completing my functional programming university course using just it and a scheme port. I discoura

Thanks! As Zikes say, a little competition is good and gitlab is working out fine for me. I used to be on gitorious and it got bought by gitlab so I moved. I prefer being on a platform I can theoretically port.

This is entirely undesirable. First of all, char16_t and char32_t are kinda useless as there's no standard interfaces using them, and there's no conversion functions to and from wchar_t. Secondly, no, you're asking for a mass

I deliberately didn't write that to avoid the page going stale when OS X adds it. But OS X is behind the times and that's harmful. POSIX 2008 has been out for years and most of the lacking features are trivial to add. They're

As in the article, strncpy has valid uses, but it's widely misunderstood due to the poor name. strlcpy is what the name suggests. People are also surprised by the zero padding.

mbtowc isn't necessarily thread safe, it's better to recommend mbrtowc.

by sortie 11y ago
Just use setlocale(LC_ALL, "") in main, and use mbrtowc to translate from whatever the system encoding is into the wchar_t type. There's no need to bake assumptions about the system encoding into most programs.

char16_t and char32_t are useless. The C standard declares functions in <uchar.h> for converting them to and from char, but not wchar_t. The conversion to char may be lossy depending on the platform. No other interfaces uses those typ

No, it's important to understand the distinction between char and wchar_t. Both are relevant, but in different contexts. char should be considered a byte type to pass around UTF-8 with. This is the appropriate level for the large major

gnulib is atrocious beyond belief though. I hear GLib tends to abort your process on OOM, though I haven't done my research on this library, so I would be careful using these to develop reliable software.

Whether C is appropriate is highly depending on the project and context. Higher level languages offer a lot and should be used when appropriate. But when C is appropriate, and these problems arise, which they will in any C codebase of appre

I use that POSIX 2008 edition myself, and the PDF edition that I got through my university library subscriptions. I simply look up interfaces and headers in it. It's not a gentle introduction though to POSIX programming. But if you kno

I appreciate you actually trying my OS and leaving a comment. chvideomode really should work under VirtualBox. If there's a bug on my end, I would really like to fix it. Could you show up in #sortix on Freenode IRC for a debugging sess

I assure you there are plenty of room for designing your own operating system even if you implement POSIX. POSIX is a pretty reasonable minimal system interface for C programs. I osdev for fun and to challenge myself and I find a very ample

I'm not trying to gain users. Sortix 0.9 is not permanently installable on real hardware from itself. The upcoming release will contain an installer for permanent installation, however. You are quite simply not my audience. Even if I d

My utility function is to write a good operating system that I like. Any effort towards that goal is not wasted. If I can use it on my computers, which I can, I'm happy. Note the existence of secondary benefits. Sortix libz is a cleane

Sortix is because I want to write a good operating system that I like myself. I do like if it's generally useful.
