OutBuffer buf; buf.write_int32(123); buf.write_int32(-456); buf.write_int16(789); buf.write_int16(-1011); // print buffer contents std::cout << buf.get_data() << std::endl;
OutBuffer buf; std::string message = "Hello, world!"; buf.write_string(message); // send buffer over network send(socket_fd, buf.get_data().c_str(), buf.get_length(), 0);This code writes a string to an OutBuffer and then sends the buffer's contents over a network socket. The use of the OutBuffer allows the string to be serialized in a consistent and efficient manner. It is difficult to determine the exact package/library that provides the OutBuffer class as it may be created by developers for their specific use and not publicly available. However, there are several C++ libraries that provide similar buffer classes, such as Boost or Qt.
