I am going to redefine the question becuase i didnt mention that i am sending the datas by qdatastream.

I am sending the data from a little endian machine to a big endian, but i have read that qdatastream is setted in bigEndian by default , so isnt it neccessary tranform the datas alocated in little endian to big endian? because i understand that this is done by qdatastream type in default mode.
