Want help using struct pointers

I want to be able to use pointers to manipulate a struct I have defined as opposed to returning a struct object from the method. While I am not horribly concerned about optimization at this stage, I used to know how to this this.

Constants and typedef code, from header file:

Code:

---

#define FIARROWS 6
#define FIARCOLUMNS 7
typedef enum {PLAYER1, PLAYER2, PLAYER3, PLAYER4, EMPTY} player;

typedef struct
{
        int COLUMNS;
        int ROWS;
        int locations[FIARCOLUMNS][FIARROWS];
} FIARBoard;

---

I understand the struct may seem unnecessary at this point, but it has a purpose that should evolve as the code does. The goal of the function I want help with is to set every location in the array to EMPTY.
My code attempt.

Code:

---

void FIARClearBoard (FIARBoard* board)
{
    for (int x=0; x<FIARCOLUMNS; x++)
    {
        for (int y=0; y<FIARROWS; y++)
        {
            board.locations[x][y] = EMPTY;
        }
    }
}

---

This method produces the error "Request for member 'locations' in something not a structure or union".

How should I approach this differently?

board is a pointer so use board->locations

Thanks! I haven't used C in a long time, but it works better then C++ when programming for both windows API and Cocoa.
