I'm using std::ostringstream to serialize data to send it through sockets later. Now I'm using std::ostringstream::str() function to get access to the data, but I would like to avoid copying the data.

Is this possible to get access to the underlying data buffer in std::ostringstream (const char* or something similar)?

Are you unable to store the string returned by `str()` somewhere and pass that instead? – Vittorio Romeo Feb 27 '17 at 17:49
@VittorioRomeo calling str() creates a copy - I would like to avoid this. – Mircea Ispas Feb 27 '17 at 17:51
