Reading a data structure that has vectors from a binary.

[sotiris]

I'm writing a Class structure to a binary file that has the following format:

class FUN
{
public:
long ID;
uint16_t Count;
vector<vector<vector<uint16_t>>> Values;

FUN(){};
~FUN(){};

};

I write this to my file using
FUN fun;
//Populate the fun object with data...
ofstream CurrentOutputFile;
CurrentOutputFile.open(OutputFile.c_str(), ios::out | ios::binary);
CurrentOutputFile.write ((char*)&fun, sizeof(FUN));
CurrentOutputFile.close;

I try to read the data using

CurrentInputFile.open(File.c_str(), ios::in | ios::binary);
CurrentInputFile.seekg(0, ios::beg);
FUN *myFUN = new FUN;
CurrentInputFile..read( (char *) myFUN, sizeof (FUN) )
cout << myFUN->[0]0][0] << endl;
delete myFUN;
CurrentInputFile.close();


I get a segmentation fault when I try to read the uint16_t.

I am a c++ noob so I was wondering if this is even possible to do, or even if its efficient to do. If not, any suggestion on how to model my class?

I may not quite understand the question, but....
if you want to read the value of Count, initialise it first or strange things can happen.....
