如何从函数返回指向char[][][]的指针？

#include <stdio.h>
#include <stdlib.h>

char*** createArray(int size1, int size2, int size3) {
    char*** ptr;
    int i, j;

    ptr = (char***)malloc(sizeof(char***) * size1);
    for (i = 0; i < size1; i++) {
        ptr[i] = (char**)malloc(sizeof(char**) * size2);
        for (j = 0; j < size2; j++) {
            ptr[i][j] = (char*)malloc(sizeof(char*) * size3);
        }
    }

    return ptr;
}

int main() {
    int size1 = 2, size2 = 3, size3 = 4;
    char*** array = createArray(size1, size2, size3);

    // 使用array进行操作

    // 释放内存
    int i, j;
    for (i = 0; i < size1; i++) {
        for (j = 0; j < size2; j++) {
            free(array[i][j]);
        }
        free(array[i]);
    }
    free(array);

    return 0;
}
