copying an **int array passed through parameters

Is there any other way to copy an array or rather 'pass by value'?

Heres what im currently doing, I do not like it much... (I need to work with the data in array but I can't have it changed once the method returns.

Code:

---

int dijkstra(int buildings,int **tempEdges)
{
    //crude way of copying an array
          int **edges;
        edges = new int*[buildings+1];
        for(int i=0;i <= buildings;++i)
                edges[i] = new int[buildings+1];
        for(int i=0;i <= buildings;++i)
        for(int j=0;j <= buildings;++j)
                edges[i][j] = tempEdges[i][j];

//jumble array around to work with it
//return value
}

Any ideas?

For primitive and POD types you can use the C function memcpy to copy blocks of continuous memory.

I'd use a std::vector. Every element in the vector will be copied if you pass it by value.
