What I would do first is to print the result byte by byte each as
hexadecimal number.
If you can I would additionally populate the C-structure with numbers,
which are easier to follow.
Example:
signature = "ABC" // same as 0x41 0x42 0x43
version = 0x61626364
attr_count = 0x65667678

Quick fix:

then the rest can stay the same, struct.calcsize('3sII') expects a 12

Hi,
I have a script that I want to use to read some binary lon and lat data
that was written with a C program. My script looks like this:
lat = open(lat_file,'rb').read()
lat = Numeric.fromstring(lat)
print len(lat)
print lat[0]
Results:
1476225
-995001790

Then you're going to have to do some bit-bashing.
