Indeed, but why Would you like to? There's two prevalent solutions: for efficiency: in order to avoid my function calls being Digital for security: to make sure that my class is not applied as a foundation class (one example is, to make sure that I am able to copy objects without dread of slicing) In my encounter, the efficiency purpose is generally misplaced fear. In C++, virtual functionality calls are so quickly that their real-environment use for a category developed with virtual features isn't going to to supply measurable operate-time overheads in comparison with different answers making use of everyday operate phone calls. Notice the Digital perform phone mechanism is typically employed only when calling by way of a pointer or a reference. When contacting a functionality directly for the named object, the Digital perform course overhead is well optimized away. When there is a real will need for "capping" a class hierarchy to stay away from Digital operate calls, one particular could check with why Those people features are virtual to begin with.
In the decision to just accept(), the server is place to sleep and when for an incoming client request, the three way TCP handshake* is finish, the operate acknowledge () wakes up and returns the socket descriptor representing the client socket.
