Also, can you please post the output of the following code snippet?

<test script>
from ctypes import *

class X(Structure):
    _fields_ = [("a", c_short, 4),
                ("b", c_short, 4),
                ("c", c_int, 24),
                ("d", c_short, 4),
                ("e", c_short, 4),
                ("f", c_int, 24)]

print X.a
print X.b
print X.c
print X.d
print X.e
print X.f
