e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * We have two ways of saving/loading states.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * First which is being used atm, just pure saving/loading of structures.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * The drawback is we have to deal with all the pointers around those structures,
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * we'd have to update this code if we'd change state tracking.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * On the bright side it's fast, though it's not really needed as it's not that often operation.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * It could also worth to split those functions into appropriate parts,
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * similar to the way context creation is being done.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * Second way would be to implement full dispatch api table and substitute diff_api during saving/loading.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * Then if we implement that api in a similar way to packer/unpacker with a change to store/load
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * via provided pSSM handle instead of pack buffer,
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * saving state could be done by simple diffing against empty "dummy" context.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * Restoring state in such case would look like unpacking commands from pSSM instead of network buffer.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * This would be slower (who cares) but most likely will not require any code changes to support in future.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * We will reduce amount of saved data as we'd save only changed state parts, but I doubt it'd be that much.
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * It could be done for the first way as well, but requires tons of bit checks.
