item=unpack( "IIII", rec, offset)
How about making offset a standard integer, and change the signature to return a tuple when it is used:
item = unpack(format, rec) # Full unpacking offset = 0 item, offset = unpack(format, rec, offset) # Partial unpacking
The second item in the returned tuple being the offset of the first byte after the end of the unpacked item.
Cheers, Nick.
