Python subprocess Popen windows error code

Question

I'm running a py script on a separate process via subprocess.Popen Then I call

(proc_out, proc_err) = proc.communicate

and also read the return code

proc.returncode

While proc_err is None the return code is 3221225738

Does anyone know what it means or how to get an understandable error? Thanks

chances are that is the positive representation of a 32bit negative number? — LhasaDad

it may be a value relative to the os or the process started. the hex value of the number is this: ‭C000 010A‬ — LhasaDad

Added an answer. you might want to give more context on the calls made (more surrounding code). — LhasaDad

STATUS_PROCESS_IS_TERMINATING (0xC000_010A) would normally be translated to ERROR_ACCESS_DENIED (5) for a WinAPI call. Either the process failed during initialization, or it died on an unhandled exception while running. Offhand I can't think of a system call that would raise an exception with that status code, so I'll take a wild guess that something went wrong that caused the console host process (conhost.exe) to terminate while the base API was setting up the console connection. Try running it with creationflags=subprocess.DETACHED_PROCESS and stdin=subprocess.DEVNULL. — Eryk Sun

The most likely meaning of the return code is that its the HEX value C000010A which I found a description of this for:

Error code0xC000010A
TypeWindows NT Status Code
DescriptionSTATUS_PROCESS_IS_TERMINATING
Comments

EventID.Net
In programming terms, this is a message that is returned when a function is trying to obtain a reference (a handle) to a certain process but that process is actually terminating (shutting down).

best guess is its trying to access the proces after it has finished....

debugging further I found this other error: (5, 'AssignProcessToJobObject', 'Access is denied.') I'm using win32job.AssignProcessToJobObject(self.job_object, hProcess)
