c++ - 如何返回指向多维数组的指针？

Question

我有一个 C++ 模板类，如下所示:

template <typename T, int xMax, int yMax, int zMax>
class Volume {
public:
    T*[64][64] getDataPointer() {return data;} //compiler doesn't like this line
private:
    T data[xMax][yMax][zMax];
};

typedef Volume<unsigned char, 64, 64, 64> Chunk;

编译器不喜欢我对 getDataPointer() 的返回。我想返回我将用于传递给此函数的相同类型:

void perlin2D(unsigned char (*chunk)[64][64])

谁能告诉我怎么做？

将签名更改为:

T (*getDataPointer())[64][64] {return data;}
