Passing a Multidimensional array in a function (NOT MFC)

HELP !!!!!

I have 2 modules, module 1 creates and populates a tree view and module 2 scans the network and store the results in a mutlidimensional array. How can i pass the  array created in module 2 to module 1 ????

This is my array:
char str_Array[10][512]; Defined golbally in module 2

Module 1: Creates Tree View
static BOOL PopulateTreeItems(HWND hWndTreeView)

Module 2: Scans network

int scanNetworkNow(HWND hWnd)


I'm developing in eVC++ (NOT MFC)

If str_Array is defined globally in module 2, then module 1 should be able to access it if you give it an extern reference like:

extern char str_Array[10][512];

outside of any function.

Hello,

I have a example for passing two-dim array to function. I got it from Denis Ritchi's book and add code to it.

// CODE CODE CODE CODE

#include <iostream.h>
void print_m34(int m[3][4]);
void print_mi4(int m[][4], int dim1);
// void print_mij_v1(int m[][], int dim1, int dim2); // error
void print_mij_v2(int** m, int dim1, int dim2);

void main()
{
      int n[3][4] = { {11,12,13,14},
                              {15,16,17,18},
                              {19,20,21,22} };

      int iTest = 0;
      
      cout << "two-dimensional array\n\n";
      print_m34(n);
      print_mi4(n,3);
      // print_mij_v1(n,3,4);
      print_mij_v2((int**)n,3,4);
      iTest = n[0][0];
      cout << "\n\n" << iTest << '\n';

      return;
}

void print_m34(int m[3][4])
{
      cout << "in print_m34 function:\n";
      for (int i = 0; i<3; i++)
      {
            for (int j = 0; j<4; j++)
            {
                  cout << ' ' << m[i][j];
            }
            cout << '\n';
      }
}

void print_mi4(int m[][4], int dim1)
{
      cout << "in print_mi4 function:\n";
      for (int i = 0; i<dim1; i++)
      {
            for (int j = 0; j<4; j++)
            {
                  cout << ' ' << m[i][j];
            }
            cout << '\n';
      }
}

/*
void print_mij_v1(int m[][], int dim1, int dim2)  // error
{
      cout << "in print_mij_v1 function:\n";
      for (int i = 0; i<dim1; i++)
      {
            for (int j = 0; j<dim2; j++)
            {
                  cout << ' ' << m[i][j];            // surprise
            }
            cout << '\n';
      }
}

*/

void print_mij_v2(int** m, int dim1, int dim2)
{
      cout << "in print_mij_v2 function:\n";
      for (int i = 0; i<dim1; i++)
      {
            for (int j = 0; j<dim2; j++)
            {
                  cout << ' ' << ((int*)m)[i*dim2+j];            // obscure
            }
            cout << '\n';
      }
}

// END CODE
