If you allocated memory for 512 byte filenames then you must copy the
string into the array at the right address, something like:

/* Note that the 512th byte must be '\0', to ensure null terminated results. */
strncpy (&array[0][0], "a.txt", 512 - 1);
strncpy (&array[0][1], "b.txt", 512 - 1);

My advice is:
    o Before you do anything else, learn your pointer arithmetic
    o Once you know your pointer arithmetic, dont bother allocating
      your array by hand and doing the math by hand, just use GArray;
      at least you will know what is going on under the hood of GArray
      (which is the most important part).
