I don't know if it is faster, but maybe constructing objects with
the `ctypes` module let you write more readable code as you can treat and
access C ``struct``\s like objects.

For the "fast" part of the question you might consider actually measuring
your program, as the task may be I/O bound i.e. Python may be faster than
the data comes in regardless of which module, `struct` or `ctypes`, you
use to tear apart and access the data.
