what exactly is your goal... and what is your problem. if you could be a little more specific with your questioning we may be able to help better.

the problem is that the following code doesn't work:

   tcp_init();
   pcb = tcp_new();
   tcp_bind(pcb,&ipaddr, 70);
   pcb2=&tcp_listen(pcb)
   tcp_accept(pcb2, conectado());

First of all I'm using the STANDALONE lwIP, because I need an easy single threaded code and no OS. At the begining I tried to use MICRO/OS but I couldn't succed.

in the code:

I create a tcp entity, after I blind it, and finally I put it to listen using the function tcp_listen. I expect that in this point the code stops the execution waiting for a remote connection and after executes "conectado" through the "tcp_accept" function.

But, this doesn't work, the code doesn't wait for the remote connection and it is executed until the end.

in my opinion, one step is missing, but i don't know which or where. could you help me or give me a piece of advice such as an example?

The main goal is to establish an elemental TCP/IP connection between the nios2 processor, working as server, and a PC, working as client.

Thank you for your time!!
