Read data to double linked list in C

[CMoose]

I'm trying to write a program that reads data from a text file and stores it into a doubly linked list. I then want to be able to edit or sort the list.
However, I'm having trouble getting started with reading the file into a doubly linked list. Any advice would be appreciated. Thanks!!

Hi,
r u facing issues in reading a file or storing the value into the Linked list.
Have you written the linked list?
Please provide more info
Thanks

Simple write a program for doubly link list. I guess your node would look something like this

Struct Node{
 
struct Node * Next;
struct Node * prev;
int data
};

When ever You create a new node just read the data from file using fscanf

fscanf(FilePtr,"%d", &(Node->data));

This is what I have so far

#define GLEN 20
#define TLEN 25
#define RLEN 6
 
struct movie_s {
 char title[TLEN];
 char genre[GLEN];
 char rating[RLEN];
 unsigned short year;
 unsigned short score;
 struct movie_s *prev;
 struct movie_s *next;
};
typedef struct movie_s movie_t;
 

but now that I have that, I don't know what to do with it. How do I use this structure to edit the list? Where is the data from the text file being read into the list?

i was thinking that i could do a while loop to read the file until the end of the file, but how do i format a while loop with my structure?

while(fscanf(ifile, .... i don't know what's next?

[CMoose]

char *new_record (char *buffer) 
 {
    char *rec = (char *) malloc (GLEN+1);
 
    strcpy (rec, buffer);
    return rec;
 }

how do i call this function in main? or any similar function to edit the list?

You could write your own helper function. In your while loop, instead of calling fread or fscanf, call your helper function. This helper function can read into the title array, genre, rating, and other fields of a movie_s passed to it.
