How to initialise a stringstream from a vector char

Question

currently I am using a boost char array

boost::array<char, 512> received_data;
std::istringstream ss_(received_data.data()); 

but what if my received_data was a std::vector<char> received_data(512);

how would I then get this data to my std::istringstream ss_?

There is no easy (and correct) way to do this properly. To do it right you either have to use boost or implement your own streambuf (which isn't too hard). – Beefwood

Answer 1

The istringstream takes a string, and a string can be made from two char iterators, like this:

istringstream iss(string(v.begin(), v.end()));

This makes an unnecessary copy of the data. – Beefwood

Answer 2

std::vector<char> receivedData(512);

std::istringstream iss(&receivedData[0]);

Good if there's no 0s in the data and the last is a 0. – Krick

If there is a 0 in the middle of the std::vector<char> then the iterator version will only take the part up to the 0 too as far as I can tell, with that said the iterator version is preferred. – Explicate
