- * An uIP application is implemented using a single application
- * function that is called by uIP whenever a TCP/IP event occurs. The

- * using the UIP_APPCALL definition.
- *
- * uIP applications can store the application state within the
- * uip_conn structure by specifying the type of the application
- * structure by typedef:ing the type uip_tcp_appstate_t and uip_udp_appstate_t.
- *
- * The file containing the definitions must be included in the
- * uipopt.h file.
