    As /u/huellenoperator notes, that this needs a pointer to a mutable string comes straight from microsoft through win32metadata. Maybe it's a mistake on Microsoft's side, but if it's not you're taking big risks.
  • Kernel Headers for Windows could soon make it into windows-rs

    Microsoft offers official "bindings" to Win32 APIs through win32metadata. However, until recently, it did not include metadata for kernel-level functions or WDK. In early 2021, an issue was raised through windows-rs regarding this limitation, but progress was slow until now. Microsoft has finally released official metadata for WDK, which can be found on the wdkmetadata repository. The latest comment on the issue thread can be found here:

    Any examples? Since the API bindings in windows-sys are generated from the metadata generated from official Windows SDK headers I'd not expect to see this kind of difference.

    There is still the occasional incredibly subtle link time fuckery in Rust.

    "Minor" semver updates to crates breaking things via e.g. unexpected MSRV bumps is pretty common too, with some resulting bitrot. That said, I agree with you that things in Rust are at least better. Imperfect, but better.

    Win32 is available as metadata to enable adoption in as many languages as possible. Are there some things missing? Yes. The Microsoft team acknowledges that and encourages asking for the things you need so they can add them to the metadata.

    Hi JB! Funny to cross paths with you in this context. I don't know if you remember me but I was a rookie programmer who got the pleasure of joining the VideoLan Conference in Dublin back in 2014, and then Paris the next year, and you were very kind to me.

    The GitHub issue title here is unfortunately misleading. I have renamed it to "ideas to improve windows header files and libc". Also, I hope it is clear that I rebutted the points made by the OP, because I completely agree with your summary that the mingw-w64 people are skilled, nice and very clever and think about all use cases.

    If any drive-by HN readers work at Microsoft, please help us with this issue:
