#includeIn this example, we create an instance of a MessageIn object and assume that it contains the BEING-ID we want to read. We then call the readBeingId method on the message object, which returns the identifier as a 32-bit unsigned integer. Based on the syntax and class names used in the code example, it appears that the package library used in this example is cppnet (presumably a C++ network library).// ... cppnet::MessageIn message; // assume a message has been received uint32_t beingId = message.readBeingId();
