subprocess.callv("somewindowsprog.exe", "some", "strange", "command", "line")
...if somewindowsprog.exe doesn't use the MS C runtime argument rules.
I'm not sure I understand what the MSC runtime has to do with the naming of call/callv.
In that case, my explanation wasn't good enough :) It's somewhat complicated. Most people will never have any problems with these issues, but I've taken care so that the API should support all cornercases.
Your examples don't work with call either, right?
They work with call if you use a string argument. That's the core of the problem: The callv function doesn't support passing a string-type args argument to the Popen constructor.
Their call() equivalents:
subprocess.call(["somewindowsprog.exe some strange command line"]) subprocess.call(["somewindowsprog.exe", "some", "strange", "command", "line"])
are just as broken, no?
Yes. You'll need to do: subprocess.call("somewindowsprog.exe some strange command line") /Peter Åstrand <astrand@lysator.liu.se>
