Hello all,
i have it ! i am happy now ;-)
here my changes for my multi_app solution.

hi all,
i like to use a multi application scenario,
i tried to implement the example from the application documentation.
but i get an error if i compile it. and my knowledge of c is quit low.
so maybe is only a c knowledge problem .
hope somone can help.
regards
kai
here my header file of the switch application who shell be called from
the stack.
#ifndef __UIP_APP_ROUTER_H__

#include <uip/uipopt.h>
//struct uip_router_state {

//};
struct uip_router_state {
enum {WELCOME_SENT, WELCOME_ACKED} state;
};
^ "empty declaration" <<<<<<<<<< error is here <<<<<<<<<<<<<<
//typedef struct uip_router_state uip_tcp_appstate_t;
#ifndef UIP_APPCALL

#endif
/* Finally we define the application function to be called by uIP. */
void uip_router_appcall(void);
void uip_router_init(void);
#endif /* __TELNETD_H__ */
and here the c file:

#include <uip/uip.h>
void uip_router_init(void){
telnetd_init();

}
void uip_router_appcall(void){
