arithmetic on pointer to an incomplete type?

I keep getting the 'arithmetic on pointer to an incomplete type' on all of the following:

Code:

---

strcpy ( dataList[i], buffer2 );

---

Code:

---

        lineLen = strlen(buffer2);
        for ( j=0; j < lineLen ; j++)
            dataList[i][j] = buffer2[j];

---

Code:

---

printf("\ngetData 7.0 : dataList[%d] : <%s>", i, dataList[i]);
getchar();

---

What am I doing wrong T-T?

Not posting enough information to definitively answer your question.

How are dataList and buffer2 declared?

Sorry ^ ^; I forgot those important details o o;

dataList is:
char dataList [5][MAX];
passed as:
fp = getData ( dataList, fp, &linesR);
recieved as:
FILE *getData ( char dataList[5][], FILE *fp, int *linesR){

buffer2 is:
char buffer2 [MAX];

Does it have to do with the fact that one is 1D and the other is 2D?

You can't do this:

Code:

---

FILE *getData ( char dataList[5][], FILE *fp, int *linesR){

---

You need to specify the rightmost dimensions, not from the left. You can leave the leftmost one empty.

>< Programming lords shoot me now.

Thanks Dave. I'll try not to be an idiot anymore, but I can't promise that o o
