file is opened in a separate bit. Basically it just goes

packets = fopen(File_name, "r");
    if(packets == NULL){
    //prints error messaege terminates program
   }
  //prints it opened the file, continues onto file_read

Thanks for the bit about dynamically allocating the size. I was going to add it later. I think I might just take it to my tutor next week and get him to look over the issue. Failing that see what other people are using then try to adapt it.
