[PATCH v10 0/4] MR6423: Implement NtQuerySystemEnvironmentValueEx, NtQuerySystemInformation SystemBootEnvironmentInformation, GetFirmwareType, GetFirmwareEnvironmentVariable*
ntdll: - `NtQuerySystemInformation` `SystemBootEnvironmentInformation` - `NtQuerySystemEnvironmentValueEx`
kernel32: - `GetFirmwareType` - `GetFirmwareEnvironmentVariableExA` - `GetFirmwareEnvironmentVariableExW` - `GetFirmwareEnvironmentVariableA` - `GetFirmwareEnvironmentVariableW`.
The code is needed to check SecureBoot status, security systems and for example to check the licenses of software that can use efi variables. The behavior matches the behavior of Windows 11. And the output is no different on wine and Windows 11.
Example:
```C #include <stdint.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <windows.h> #include <winnt.h> #include <winternl.h> #include <winbase.h> #include <shlwapi.h> #include <securitybaseapi.h>

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=148250
Your paranoid android.

Probably better to convert this string to utf16, then call the W function. That'd not only remove that GUID conversion function (I'd rather not review that amount of math - I think even GCC will complain that, unclear precedence warnings on | and +), but also make future maintenance easier. Yes, it'll copy and convert around things a little more. Who cares, this isn't performance sensitive. If you want to remove the allocations, you can put one in NtCurrentTeb()->StaticUnicodeBuffer, A/W conversions is exactly what it's for. (Though there's only one, so you'll need pointer math or allocations for the other one.)
@Alcaro I have already fixed the compiler warnings about arithmetic operations.
