Nico added the comment: Yeah I see the point. To me it does make no sense because even in the windows API they seam to not know whether to use a ulong or a uint nor does this reflect the actual depiction within the program. However it is probably not worth implementing a flag for that nor

Eryk Sun added the comment: In the Windows API, errors and exit status codes are all unsigned 32-bit integers. See SetLastError, GetLastError, ExitThread, ExitProcess, GetExitCodeThread, and GetExitCodeProcess. Even signed NTSTATUS and HRESULT values are commonly displayed as non-negative

[issue41386] Popen.wait does not account for negative return codes

New submission from Nico : Following problem occurred. A C style program can have negative return codes. However this is not correctly implemented in the Windows API. Therefore it is being returned as unsigned long by the API hence it leads to ambiguity while comparing return codes. For
