gtk containers

The gtk glib library includes some standard container like linked lists…

/* Compile with cc doubly.c  `pkg-config --cflags --libs gtk+-2.0`  */

#include <glib.h>
#include <string.h>
#include <stdio.h>

void myfunc(gpointer data, gpointer user_data)
{
    printf("value %s\n", (char *)data);
}

int main()
{
    GList *list = NULL;
    GList *it = NULL;

    list = g_list_append(list, "one");
    list = g_list_append(list, "two");
    list = g_list_append(list, "three");

    for (it = list; it != NULL; it = it->next)
        printf("looping - %s\n", (char *)it->data);

    /* or alternatively  */

    g_list_foreach(list, (GFunc) myfunc, NULL);

    printf("length of list is %d\n", g_list_length(list ));
    return 0;
}
