如何将具有可变列数的二维数组传递给函数？

#include <stdio.h>

void processArray(int *arr, int rows, int cols) {
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            printf("%d ", *(arr + i * cols + j));
        }
        printf("\n");
    }
}

int main() {
    int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
    int rows = sizeof(arr) / sizeof(arr[0]);
    int cols = sizeof(arr[0]) / sizeof(arr[0][0]);

    processArray(&arr[0][0], rows, cols);

    return 0;
}
