[python-win32] Re: How do I re-assign stdin and stdout

[Roger Upole]

You'll need to set win32con.STARTF_USESTDHANDLES in the dwFlags member of  PySTARTUPINFO.
Also, the PySECURITY_ATTRIBUTES in the call to CreateFile has to have bInherit set to True,
and the bInheritHandles parm to CreateProcess has to be True.
