someone help? strtol?

HI,

I need to tokenize the data from a file named books.dat to load into the system...anyone got any clues?! some help would be greatly appreciated

Book data file format:
<id>:<title>:<author>:<year>:<price>:<count>

Example:
1:A Book on C:A. Kelly:1997:89.95:7
2:Java Software Solutions:J. Lewis:2000:79.95:2
etc...

n so far my code is looking like this...

Code:

---

#include "bookstore2.h"

#define NUM_ARGUMENTS 3
#define MAXSTRING 100
#define ARRAYSTR 100

int main(int argc, char **argv)
{
  int tempID, tempYear, tempPrice, tempCount;
  char tempString[MAXSTRING], DELIMITER[] = ":";
  char* ptr;
  char* tempArray[ARRAYSTR];
  char* booksFile;
  char* salesFile;
  BookListType booklist;
  FILE* fp;

  /*when arguments are wrong*/
  if(argc != NUM_ARGUMENTS)
  {
      fprintf(stderr, "Argument error\n");
      return EXIT_FAILURE;
  }
  else
  {
      /*check what arguments were passed*/
      if((argv[1] == "books.dat") && (argv[2] == "sales.dat"))
      {
        loadData(&booklist, booksFile, salesFile);
        fp = fopen("books.dat", "r");

        /*read data from books.dat*/
        ptr = strtok(tempString, DELIMITER);
        tempID = strtol(ptr, &tempArray, 10);
        newBook->id = tempID;
     
        ptr = strtok(NULL, DELIMITER);
        strcpy(newBook->title, ptr);

        ptr = strtok(NULL, DELIMITER);
        strcpy(newBook->author, ptr);

        ptr = strtok(tempString, DELIMITER);
        tempYear = strtol(ptr, &tempArray, 10);
        newBook->year = tempYear;

        ptr = strtok(tempString, DELIMITER);
        tempPrice = strtol(ptr, &tempArray, 10);
        newBook->price = tempPrice;

        ptr = strtok(tempString, DELIMITER);
        tempCount = strtol(ptr, &tempArray, 10);
        newBook->count = tempCount;

        if(fp == NULL)
        {
            printf("Can't open file\n");
            exit(1);
        }
        fclose(fp);
      }
  }

  return EXIT_SUCCESS;
}
