Question

I’m trying to read a text file and store each line in a node of a link list of type void*.
Here’s the header file of the list.

#ifndef LINKEDL
#define LINKEDL

struct node_s {
    void *data;
    struct node_s *next;    
};

struct node_s *node_create(void*);
struct node_s *list_insert_after(struct node_s*, void*);
struct node_s *list_insert_beginning(struct node_s*, void*);
int list_remove(struct node_s*, struct node_s*);
int list_foreach(struct node_s*, int(*)(void*));
int printstring(void *s);


#endif

All the linked list functions have been thoroughly tested, so I guess the problem is with how I use it. What I want to achieve is the have one line in each node and what I have now is last line in every node. I guess it has something to do with the char pointers but have already spent two hours on that without a spectacular breakthrough, so maybe someone could help?
Also the list I use is a modified list as seen here.

 if (file == NULL)
 {
    perror("Error opening file");
 }
 else 
 {
     char mystring[SIZE];
     char temp[SIZE];

     list = node_create((void*)mystring);
     current = list;
     while (fgets(mystring, SIZE, file) != NULL)
        {
            strcpy(temp, mystring); 
            printf("%d\t%s",counter++,temp);
            current=list_insert_after(current, (void*)temp);                    
            }
            fclose(file);

        }

UPDATE:
Thank you All.

Answer 1

Remove the line:

strcpy(temp, mystring); 

And change the line:

current=list_insert_after(current, (void*)temp);

To

current=list_insert_after(current, strdup(mystring));
