            Bug ID: 50405
           Summary: Missing ability to read Evironment Block and
                    Environment Block Size from any Process ID kernel32
           Product: Wine
           Version: 5.0
          Hardware: x86-64
                OS: FreeBSD
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs at winehq.org

This works on Windows for me, but in WINE I get an empty string:

https://github.com/time-killer-games/libprocinfo/blob/57ca23b1896a68f7b349bfc15607d62f91aa2a7c/ProcInfo/Win32/procinfo.cpp#L77

Requires using a private API. I noticed you guys implemented a different
private API which allows you to get the Current Working Directory from an
arbitrary Process ID, so that shows you guys aren't against implementing
private API's.

So anyway, it would be nice to have this, as my libprocinfo library relies on
this  as one of its core features. It can also help debugging Windows processes
runing through WINE, for those who need that sort of thing.

I use it for inter-process communication and to avoid sockets, personally.

See the function env_from_pid(process_t pid) in that source file, for more
details on the implementation. Who knows, maybe I'm doing something wrong and
it could be pure luck it works on Windows natively, but I really doubt that.
