Hi,
   I changed example "tcp_echo_multithread" to test how many sockets i
can open simultanously. The code is much simipler than it before. It
does nothing excpet waiting for 4 connections and CLOSING THEM IN
CLEANUP_MODULE(). The problem is that it takes too long time to accpet
3th connection and when i rmmod it prints a lot of p != NULL.Why?
Thanks!


This is my code:
--------------------------------------------------------------------
#include <linux/module.h>
#include <linux/kernel.h>
#include "lwip/sys.h"
#include "lwip/api.h"
#include <rtl_sched.h>
#include <rtl_debug.h>

#define NUM_OF_CONN 4
struct netconn *newconn[NUM_OF_CONN];

static void 
tcpecho_thread(void *arg)
{
  struct netconn *conn;
  int i;

   /* Create a new connection identifier. */
  conn = netconn_new(NETCONN_TCP);

  /* Bind connection to well known port number 7. */
  netconn_bind(conn, NULL, 7);

  /* Tell connection to go into listening mode. */
  netconn_listen(conn);

  for(i=0;i<NUM_OF_CONN;i++) {
    newconn[i]=netconn_accept(conn);
    rtl_printf("%d accepted\n", i);	
  }
}

int init_module(void){
  printk("\n Multithreaded TCP echo server inserted\n");
  sys_thread_new(tcpecho_thread, NULL, 0);  
  return 0;
}

void cleanup_module(void){
  int i;
  for(i=0;i<NUM_OF_CONN;i++){
    netconn_close(newconn[i]);
    netconn_delete(newconn[i]);
  }
  printk("\n Multithreaded TCP echo server removed\n");
}
