seems to work fine boost::serialization could do it. Note: write the archive version first and then do register_types

C data structure to disk

C data structure to disk

help you fix your problem The basic pieces here are:
The C file I/O routines are fopen, fwrite, fprintf, etc. Copying pointers to disk is useless, since the next time you run all those pointer values will be crap. So you'll need some alternative to pointers that still somehow refers disk records to each other. One sensible alternative would be file indexes (the kind used by your C I/O routines like fseek and ftell).

I wish did fix the issue. If you're going to be working with larger amounts of data, it's probably anyway better to give Core Data a try, it's after all not that complicated and there's a plenty of good tutorials where you can learn it. There are different settings for the storage type, you can either use a sqlite database or an xml file.
According to the guys from Apple, it should be fast and memory effective to use Core Data in contrast to self-made solutions, so it's a preferred way to go.

To fix this issue Any of these solutions would be great.
If you want it to be crash-proof, do your writing to a temporary file, and only replace the original file after the write is complete. The worst scenario is that you have two valid files.

this will help Is it possible to save a variable from C# to disk so that you are able to use it later in another instance of your project?
code :
public void SerializeObject<T>(string filename, T obj)
   {
      Stream stream = File.Open(filename, FileMode.Create);
      BinaryFormatter binaryFormatter = new BinaryFormatter();
      binaryFormatter.Serialize(stream, obj);
      stream.Close();
   }

   public T DeSerializeObject<T> (string filename)
   {
      T objectToBeDeSerialized;
      Stream stream = File.Open(filename, FileMode.Open);
      BinaryFormatter binaryFormatter = new BinaryFormatter();
      objectToBeDeSerialized= (T)binaryFormatter.Deserialize(stream);
      stream.Close();
      return objectToBeDeSerialized;
   }

[Serializable]
struct MyStruct
{
    byte[] ByteData;
    int MyInt;
    double MyDouble;
}

This might help you Yes, there is a way. You can store your data using NSKeyedArchiver and NSKeyedUnarchiver. NSKeyedArchiver is used to save your data. An example:
code :
[NSKeyedArchiver archiveRootObject:counters toFile:filePath];
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) {
    counters = [NSKeyedUnarchiver unarchiveObjectWithFile:filePath];
}
