Store struct elements

As imamLL is very versatile in storing any type of data into a list, you can store struct into an element like shown in the following code example:

include <stdio.h></stdio.h>

include <stdlib.h></stdlib.h>

include <string.h></string.h>

include "imamll.h"

struct Person {
char name[24];
double age;
double weight;
double height;
};

struct imamLL People_list = NULL; / Pointer to hold list /
struct imamLL_element person = NULL; / Pointer to hold individual element /
unsigned long c;

int main (int argc, char* argv[])
{
printf ("Allocating memory for list\n");

People_list = imamLL_list_create();

if (People_list == NULL) {
    printf ("Can not create the list\n");
    exit (1);
}

if ((person = imamLL_element_add (People_list, sizeof(struct Person), AT_END)) == NULL) {
    printf ("Can not add element");
    printf ("Freed list, returned %d\n", imamLL_list_destroy (People_list));
    exit (1);
}
strcpy (((struct Person *)person->data)->name, "Md Imam Hossain");
((struct Person *)person->data)->age = 27.0;
((struct Person *)person->data)->height = 180.0;
((struct Person *)person->data)->weight = 67.0;

printf ("Allocated: %lu Bytes\n", People_list->size);

if ((person = imamLL_element_add (People_list, sizeof(struct Person), AT_END)) == NULL) {
    printf ("Can not add element");
    printf ("Freed list, returned %d\n", imamLL_list_destroy (People_list));
    exit (1);
}
strcpy (((struct Person *)person->data)->name, "Md Salim Hossain");
((struct Person *)person->data)->age = 22.0;
((struct Person *)person->data)->height = 182.0;
((struct Person *)person->data)->weight = 75.0;

printf ("Allocated: %lu Bytes\n", People_list->size);

while (1) {
    person = imamLL_element_get_next (People_list);
    if (person == NULL) break;
    printf ("*Person*\n");
    printf ("Name: %s\n", ((struct Person *)person->data)->name);
    printf ("Age: %lf\n", ((struct Person *)person->data)->age);
    printf ("Height: %lf\n", ((struct Person *)person->data)->height);
    printf ("Weight: %lf\n", ((struct Person *)person->data)->weight);
}

printf ("Freed: %d elements\n", imamLL_list_free (People_list));
printf ("Freed list, returned %d\n", imamLL_list_destroy (People_list));

return (EXIT_SUCCESS);
