Need help in Python Wrapper for EWFAPI from XPe

[P Boy]

I am trying to build a wrapper for the EWFAPI running on XPe. My first
attempt was to use SWIG, but run to trouble with all these windows
types such as WCHAR, DWORD, LPWSTR, ...

I then searched further and found out about the ctypes module. However,
some functions returns pointer to struct in ewfapi.dll. How do get into
the elements of struct pointer, recursively, if possible?

Thanks for any help in advance.

Oh, writing a wrapper on top of ewfapi is an option, but it would be
painful and time consuming.
