fscanf causing a crash

I am using a simple file format, so I want to use fscanf to read the items in the file.

The format:

a string of words
an_integer<tab>another_integer
an_integer<tab>another_integer

and so on...


I get the first line fine with fgets, and then the second line with:

fscanf (infile, "%d", &int1);
fscanf (infile, "%d", &int2);

But I cannot get the third by repeating this code. How can I get to the new line?

Thanks for any help.

Why not just get all the lines with fgets() and parse them with sscanf() ?

Working pretty smoothly now, except the last line where I get a bunch of integers from the same line using:

Code:

---

        for (i=0; i<theListSize; i++)
            sscanf(theLine, "%d", &theList[i]);

---

I read the first integer over and over.

Yes, you would do. You could use strtok() or some such, or if you know how many integers you could have on the line, you can use something like:

Code:

---

    x = sscanf("%d %d %d %d", &theList[i], &theList[i+1], &theList[i+2], &theList[i+3]);
    i += x-1;

Shouldn't this code be able to fetch me all the integers on a line containing:

"1 2 3 4 5 6 7 8 9 10 11 12" without quotes?

Code:

---

        char * pch;
        pch = strtok(theLine, " ");
        while (pch!=NULL)
        {
              printf ("%s\n",pch);
            pch = strtok(theLine, " ");
        }

---

It gets me the first integer, 1, and repeats forever.

Ehm, strtok should be given "NULL" if you want to continue finding from where it last started - or you could use "pch".

Oops! Works like a charm, thanks.
