At the begining, i planned to directly read through the original datas. But finally i choosed another method. once the get_first_data_point is called, i'm locking the structure with a mutex, then duplicate all the elements in the list, and use the copy insteed of the original one. Once it's done, i release the mutex, which allow other thread to update it again.
