How do you pass a 2D array of objects to a function? C++

Question

So I have this:

class Component
{
public:
   int label;
   int order;
};

Later in my code I created a 2D array named

Component pixel[][cap]

and initialized its size with user input. Now I am trying to pass it to my function named imageDFS. I tried to use

void imageDFS(Component **)

and

imageDFS(pixel)

but I still receive compiling (codeblocks) errors.
