working with void ** (NOOB)

I'm a total beginner... so please go easy on me

i have a function that gets some parameters, i'm interested in two of them.
one is void **args
and one is int nargs

The first is probably an array, and the second one is the number of items in the array.
assume that I know that all the items in the array are int.

how can I access their values?

Thanks

I suppose you have to revert all the steps that it took to call the function with the original data.

For example:

Code:

---

#include <cstdio>

void foo(int count, void** arr)
{
    void* vp = *arr;    //dereference to obtain void pointer
    int* p = (int*)vp;  //and cast it back to int pointer
    for (int i = 0; i != count; ++i) {
        printf("%d ", p[i]);
    }
}

int main()
{
    int arr[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    void* p = (void*)arr; //cast to void*
    foo(10, &p);          //and pass its address
}

---

But why would you mess with the void pointers if you know they point to an int array?
