GetProcessHandleFromHwnd missing from SDK, metadata

[mzdk100]

Suggestion

I need to use the GetProcessHandleFromHwnd function, but it was not found in windows-rs. I tried using search and only received the following results:

PS E:\repositories\rust\windows-rs> Get-ChildItem -Recurse .\crates/\libs\windows\src | Select-String -Pattern "GetProce
ssHandle" -CaseSensitive

crates\libs\windows\src\Windows\Win32\System\Threading\mod.rs:995:pub unsafe fn GetProcessHandleCount<P0>(hprocess: P0,
 pdwhandlecount: *mut u32) -> windows_core::Result<()>
crates\libs\windows\src\Windows\Win32\System\Threading\mod.rs:999:    windows_targets::link!("kernel32.dll" "system" fn
 GetProcessHandleCount(hprocess : super::super::Foundation:: HANDLE, pdwhandlecount : *mut u32) -> super::super::Founda
tion:: BOOL);
crates\libs\windows\src\Windows\Win32\System\Threading\mod.rs:1000:    GetProcessHandleCount(hprocess.param().abi(), pd
whandlecount).ok()

PS E:\repositories\rust\windows-rs>

I'm not sure if this is a bug, so I want to know how to call this function.

This API doesn't appear in SDK headers or metadata, so I'll forward this issue to the appropriate repository. (https://learn.microsoft.com/windows/win32/winauto/getprocesshandlefromhwnd)

That said, I recommend you use GetWindowThreadProcessId instead.

[mzdk100]

Okay, then I'll use the GetWindowThreadProcessId function instead.

Yep, I wouldn't add this to metadata given that it's not generally available and there's a reasonable alternative.

[mzdk100]

I don't have any further questions, this issue can be closed.

Hey no take backs, it's documented so SDK/metadata needs an update.
