["qiufeng" <coolqiufeng hotmail com>]

Hello everyone:

  I want to know how to free the malloced memory used in a g_list?

 

here is my code

 

 

#include <stdio.h>
#include <stdlib.h>

 

#include <glib.h>

 

typedef struct
{
  char buf1[128];
  char buf2[128];
  char buf3[128];
}
buf;

 

void
freenode (gpointer data, gpointer userdata)
{
  //static int i = 0;
  //printf("%d\n", ++i);
  //free (data);
  return;

 

//  free(data);
}

 

int
main ()
{
  int i, j;
  buf *tmp;
  GList *head = NULL;

 

  for (j = 0; j < 2000; j++)
    {
      for (i = 0; i < 2000; i++)
        {
          tmp = (buf *) malloc (sizeof (buf));
          head = g_list_append (head, tmp);
        }

 

      g_list_foreach (head, freenode, NULL);

 

      g_list_free (head);

 

    }
  return 0;
}
