It's a documented option for instances of Popen, to configure a few fields in the STARTUPINFO struct that gets passed to CreateProcess. http://docs.python.org/2/library/subprocess#subprocess.STARTUPINFO STARTUPINFO struct: http://msdn.microsoft.com/en-us/library/ms686331 PC/_subprocess.c: /* note: we only support a small subset of all SI attributes */ si.dwFlags = getint(startup_info, "dwFlags"); si.wShowWindow = getint(startup_info, "wShowWindow"); si.hStdInput = gethandle(startup_info, "hStdInput"); si.hStdOutput = gethandle(startup_info, "hStdOutput"); si.hStdError = gethandle(startup_info, "hStdError"); http://hg.python.org/cpython/file/ab05e7dd2788/PC/_subprocess.c#l444 _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
