    You need to pass the pointer.

    For any array, say
    Code:
    int arr[2][3][4];
    You can prototype your function as
    Code:
    void foo ( int arr[2][3][4] );
    And define your function as
    Code:
    void foo ( int arr[2][3][4] ) {
      // do stuff with arr[x][y][z]
    }
    
    In other words, copy/paste the declaration of the array you want to pass into the function, into the parameter declaration of that function.

    Note that all these are equivalent.
    Code:
    void foo ( int arr[2][3][4] );
    void foo ( int arr[][3][4] ); // size of major dimension is optional
    void foo ( int (*arr)[3][4] ); // using explicit pointer notation
    



    The call to the function would be just
    Code:
    foo( arr );
