[lwip-users] [lwip] httpd with API

[Mikael Lundberg]

Hi guys.
I have ported lwIP to a Hitachi H8s/Cirrus CS8900A and uCOS-II.
The stack is now up and running, ping works fine.
But I have some problem with httpd, I have used the simple httpd-server that 
Adam has in his early documention, as below;

main()
{
  struct netconn *conn, *newconn;
  /* Create a new TCP connection handle. */
  conn = netconn_new(NETCONN_TCP);
  /* Bind the connection to port 80 on any local IP address. */
  netconn_bind(conn, NULL, 80);
  /* Put the connection into LISTEN state. */
  netconn_listen(conn);
  
  while(1) {
    /* Accept a new connection. */
    newconn = netconn_accept(conn);
    /* Process the incomming connection. */
    process_connection(newconn);
    /* Deallocate connection handle. */
    netconn_delete(newconn);
}

Do you think it's still work with the new lwIP-versions (Im currently using 
0.5.2)

Its seems as somethings goes wrong after the netconn_bind-function has been 
called. I belive that the function post the message with the line:
      api_msg_post(msg);
but it seems like I dont get any 'reply', and the program stands waiting for 
the message in the line after...
      sys_mbox_fetch(conn->mbox, NULL);

I have one more little question, I have defined SYS_MBOX_NULL to  NULL, but I 
am not sure of the meaning of SYS_MBOX_NULL. Will the function 
sys_arch_mbox_new return a mailbox that points at SYS_MBOX_NULL (as msg) or 
will the function return SYS_MBOX_NULL if it not able to make a mbox, or maybe 
both??    Regards  //Mikael
