I have an array of arbitrary values, so I have defined it as an array of void pointers, so I can point to any kind of information (like int, character arrays, etc).

    try this:

    data[0] = malloc(sizeof(int));
    *((int*)data[0]) = x;
    

    or

    (int) (*(data[0])) = x;
    

    don't forget to

    free (data[0]);
    

    afterwards.
