Re: Save a vector inside a structure.

Hello,

Is it possible to save a vector inside a structure to a file?

Let's say I have the following piece of code:

struct SaveData
{
int first,
int last,
std::vector<int> order;
};

If I write the structure to a binary file and read it out again the data
which should be in the vector is totally corrupt (other variables are
fine). At this moment I should be able to define a fixed size for that
vector (but I have no idea if that will work), but in the future the size
of the vector will change and I don't want this to be fixed.
I also need to be able to store the entire SaveData structure, looping
through the vector and saving each value one by one is not an option as I
also need to be able to save on some EEPROM and as far as I understand
that I'm only able to use entire structures.

I haven't found a lot of information regarding this subject so if anyone
has any ideas or suggestions, please enlighten me.
