First time using lwIP

Thanks for the pdf.

I can start the server now, but I still can't send and receive messages.

How do I use the tcp_accept anyway?

I tried something like

pcb = tcp_new();

tcp_bind(pcb, IP_ADDR_ANY, 80);

pcb = tcp_listen(pcb);

tcp_accept(pcb, ERR_OK);

while(1)

{

printf("\nI will send");

getchar();

tcp_write(pcb, "lalala", sizeof("lalala"), 0);

}

Well.... then my client can connect, but it won´t receive anything.

If I do something like:

tcp_accept(pcb, envia);

and create the function "envia" like this:

static err_t

envia(void *arg, struct tcp_pcb *pcb, err_t err)

{

int i;

for(i = 0; i < 5; i++)

{

printf("\nVou enviar");

getchar();

tcp_write(pcb, "lalala", sizeof("lalala"), 0);

}

return ERR_OK;

}

It will send the "lalala" five times when it reaches the "return".

But I want to use the tcp_write inside the main

How do I do that?

Thanks
