            Bug ID: 60068
           Summary: wminet_utils: implement GetErrorInfo()
           Product: Wine
           Version: 11.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: oleaut32
          Assignee: [e-mail]

Patch

Roon crashes during startup when querying information about attached volumes
through `System.Management`.

The crash is caused by the unimplemented `wminet_utils.dll.GetErrorInfo`
export:

```text
wine: Call from ... to unimplemented function wminet_utils.dll.GetErrorInfo,
aborting
```

The resulting .NET stack trace includes:

```text
System.Management.WbemErrorInfo.GetErrorInfo()
System.Management.ManagementException.ThrowWithExtendedInfo(...)
System.Management.ManagementObjectCollection.ManagementObjectEnumerator.get_Current()
Sooloos.Broker.FileBrowser.VolumeAttached.GetInfoFromDrive(...)
```

The application then terminates through `System.Environment.FailFast`.

The attached patch implements `wminet_utils.GetErrorInfo()` as a wrapper around
`oleaut32!GetErrorInfo()`, adds the required `oleaut32` import, and replaces
the stub export in `wminet_utils.spec`.

After rebuilding Wine with this patch, Roon no longer crashes at this point and
completes startup normally (in addition to
https://bugs.winehq.org/show_bug.cgi?id=60067).
