Thomas Heller <[EMAIL PROTECTED]> added the comment:
Currently, the _fields_ of ctypes Structures with non-native byte order
can only contain simple types (like int, char, but not pointers), and
arrays of those.
Since this is all Python code (in Lib/ctypes/endian.py) it should be
possible to extend the code to handle other types as well.
If we do this, it must be decided if a Structure (call it 'part' for
this discussion) of some byte order is contained in a _field_ of a
non-native Structure type:
- Should 'part' be inserted as is, leading to a total structure of
fields with mixed byte order?
- Should a new type be created from the 'part' _fields_, with also
non-native byte-order?
Other approaches would be possible as well...
Here is a simple patch that implements the first approach; I have not
tested if it works correctly:
