I would like to run WMI queries from Go. There are ways to call DLL functions from Go. My understanding is that there must be some DLL somewhere which, with the correct call, will return some data I can parse and use. I’d prefer to avoid calling into C or C++, especially since I would guess those are wrappers over the Windows API itself.
I’ve examined the output of
dumpbin.exe /exports c:\windows\system32\wmi.dll , and the following entry looks promising:
WmiQueryAllDataA (forwarded to wmiclnt.WmiQueryAllDataA)
However I’m not sure what to do from here. What arguments does this function take? What does it return? Searching for
WmiQueryAllDataA is not helpful. And that name only appears in a comment of
c:\program files (x86)\windows kits\8.1\include\shared\wmistr.h , but with no function signature.
Are there better methods? Is there another DLL? Am I missing something? Should I just use a C wrapper?
Running a WMI query in Linqpad with .NET Reflector shows the use of
WmiNetUtilsHelper:ExecQueryWmi (and a
_f version), but neither have a viewable implementation.
Update: use the github.com/StackExchange/wmi package which uses the solution in the accepted answer.
