ctypes: Get full contents of character array

[overdrigzed at gmail.com]

Hello!

I wanted to get the full contents of a character array stored in a
struct, i.e.
_fields_ = [...("array", c_char * 12)...]
however, ctypes seems to try to return struct.array as a Python string
rather than a character array, and stops as soon as it encounters a
null within the character array.

I ended up having to define a dummy struct
class dummystruct(Structure):
    _fields_ = []

and declare array as:
("array", dummystruct)

then use string_at(byref(struct.array), 12).

Is this really the best way of doing it? Is there no better way to
work around ctypes 'guess what you want' behaviour?

Thanks in advance,
Rodrigo
