The layout of struct coap_address_t is platform-dependent. This change introduces getter/setter functions to retrieve and modify the port component: uint16_t coap_address_get_port(const coap_address_t *addr) void coap_address_set_port(coap_address_t *addr, uint16_t port) The respective port is given in host byte order and will be converted to/from network byte order automatically.
