Actually, a std::string has no problems with storing binary data and is not necessarily null-terminated (it can contain 0 chars). The length of a std::string is stored separately. A std::string does not go looking for a 0 terminator when you pass in the length of the data in the constructor, like ingmar is doing. I think really the only problem could be that ENetPacket::data is a enet_uint8* and should be cast to a char* for the std::string constructor to accept it. So: std::string my_string ((char*) packet->data, packet->dataLength); Should compile and work fine.
