Hi,
Here's a small patch which implements NtQueryInformationProcess properly for
ProcessInformationClass set to ProcessDebugPort.
It fixes cases when ProcessInformationLength != 4, but doesn't check if a
debugger is present or not. Should it ? I don't expect that anyone would like
to run Visual Studio on Wine to debug a Win32 program :-)
