<tr><td colspan="2">An uIP application is implemented using a single application function that is called by uIP whenever a TCP/IP event occurs. The name of this function must be registered with uIP at compile time using the UIP_APPCALL definition.<p>
|
||
|
|
uIP applications can store the application state within the <a class="el" href="a00088.html">uip_conn</a> structure by specifying the type of the application structure by typedef:ing the type uip_tcp_appstate_t and uip_udp_appstate_t.<p>

The file containing the definitions must be included in the <a class="el" href="a00140.html">uipopt.h</a> file.<p>
