How many bits are in a int
WebA more complicated approach could be used for those 4 bits, e.g., by packing nine bytes (of 8-bits each) into two adjacent 36-bit words. The important point here is that memcpy () has to be able to see every bit of memory: there can’t be any bits between two adjacent bytes.
