[lwip-users] [lwip] tcp_connect

[natalia varillas]

Hello,
I want to create a new connection between the board IP: 192,168,1,2  and 
a server listening in 192,168,1,3  port 4443
This code down here dont work.It seems that never call the 
write_asnwer_to server function.

if i want to create a new connection i call tcp_connect. but Which value 
has to have last arg in the function if its a NEW connection??  


static err_t write_answer_to_server(void *arg, struct tcp_pcb *tpcb, 
err_t err)
{
  char buf[100];
  err_t new_err;
  sprintf(buf, "%s\n","Test");
  new_err=tcp_write(tpcb,(void *)buf,sizeof(buf)-1,0);
  return new_err;
}

void send_answer_to_server(char *str) {
  struct tcp_pcb *pcb;
  struct ip_addr ipaddr;
  err_t new_err;
  IP4_ADDR(&ipaddr,192,168,1 ,3); 
  pcb = tcp_pcb_new();
  new_err = tcp_connect(pcb, &ipaddr, SERVER_TO_SEND_ANSWERS_PORT, 
write_answer_to_server, NETCONN_TCP);
 
 DEBUGF_RTXC(RTXC_APPS_DEBUG, ("Connect error?=%d\n", new_err));
   
Natalia
