Possible API signature change

[kmanc]

Which crate is this about?

windows

Crate version

0.32.0

Summary

processinformationclass no longer accepts an integer as an argument. The following worked in 0.30.0 but doesn't in 0.32.0

if let Err(error) = unsafe { NtQueryInformationProcess(processhandle, 0, processinformation, processinformationlength, returnlength) } {
        panic!("Could not get the entry point with ZwQueryInformationProcess: {error}");
}

Expected behavior

I might have missed something in the changelog that explains why this is the case, but I would expect the above code to compile assuming all of the other arguments are correct

Actual behavior

Compiler returns " ^ expected struct PROCESSINFOCLASS, found integer"

Additional comments

EDIT - I said the wrong type
No response

It likely changed here: #1482

Mentioned in the release notes here: https://github.com/microsoft/windows-rs/releases/tag/0.32.0

Here are the docs for the NtQueryInformationProcess function in the windows crate: https://microsoft.github.io/windows-docs-rs/doc/windows/Win32/System/Threading/fn.NtQueryInformationProcess.html

Oh, I don't think the API signature has changed. PROCESSINFOCLASS was previously a type alias for the underlying type, i32, but is now a new struct type (#1393 and #1436).

Ahh ok, yeah that would explain it! I just changed my code to actually use the struct but was a bit confused at first when suddenly code that hadn't been changed was throwing an error at compile time. Thank you :)

Great, sorry for any confusion. 😊
