Suppose, for a moment, that when you decided to use a function, you actually read the documentation. You can write the code so that the same logic is used on all platforms if you're careful (and all platforms get the same answers). if (bind(sockfd, (struct sockaddr *) &serv_addr, sizeof(serv_addr)) < 0) error("ERROR on binding"); The bind() system call binds a socket to an address, in this case the address of the current host Error Writing To Socket Invalid Argument Browse other questions tagged c++ c sockets networking or ask your own question.
