Thread: pointer to multidimensional array

I'm trying to use a pointer to access an array, since I need to be able to switch between two identically-sized arrays. However, I get compiler errors when I try to reference an array to my pointer. Here is a sample of the code that I have, hopefully someone can tell me what I'm doing wrong.

Code:

int grid[320][240];    //my array
int *grid_ptr[][240];  //my pointer

int doSomethingWithGrid(int array[][240]); //function prototype

int main()
{
    grid_ptr = &grid;    //assign pointer to grid, compile error

    doSomethingWithGrid(grid_ptr);  //func. wont take pointer
}
