* Initializes sockaddr_in: sin_addr = htonl({input ipaddr}), sin_port = htons({input port}), and sin_family = AF_INET (sin_len is left at 0). | |||
* bind(sockfd, sockaddr_in, sizeof(sockaddr_in)); {handle error on fail} | |||
* listen(sockfd, 1); {handle error on fail} | |||
* Writes sockfd to the output sockfd state field, copies the input ipaddr u32 into state, then returns 0. | |||
* The error handling for bind()/listen() will also close the socket, when certain errors occur. | |||
