The trick is, or course, to now fill out the binary reads inside the structures, which is not easy. C is a BYTE centered langauge. It will take to create masks of the unisigned chars with a bitwise AND mask? For example, the offset is the last 3 bits so 0000 0000 0000 0111 is a mask for the last 3 bits?
