We have raw data packages from some tools. These packages contains bitfields,
arrays, simple data and so on.
We want to parse them into Python objects (structures) for analysis and
storage. I tried to use ctypes, but now I wrote myself

OK. So, it seems just like ctypes work, but don't for my needs.
Thing that bothers me anyway is the strange code, where size contains either
size (when bitsize==0) or bitsize in upper 16 bits and bitoffset in lower 16
bits

Yes. Thanks. But here is another error:
import ctypes
class X(ctypes.Structure):
_pack_ = 1
_fields_ = [
('a', ctypes.c_ubyte, 4),
('b', ctypes.c_ubyte, 4),
('c', ctypes.c_ushort, 4),
('d
New submission from Pavel Boldin boldin.pa...@gmail.com:
ctypes seems to work incorrectly with _swappedbytes_ specified.
I.e. it misses some values from buffer:
class X(ctypes.Structure):
_swappedbytes_ = 1
_pack_ = 1
_fields_ = [
('a', ctypes.c_ubyte, 4),
('b
