Win32: shortpathname to longpathname

[Jim Tittsler]

I wrap my cross platform application up with py2exe on Windows, and
have the installer associate a particular file type with it. When a
user double clicks on a document to launch my application, Windows
appears to pass me the "short" Windows pathname. How can I convert to
the long version of the pathname? (Ideally using the standard library
rather than win32all AKA pywin32.)

You want GetLongPathName:

It's not directly available on the standard library; you can either use
win32api.GetLongPathName or call it using ctypes.
