Re: Array of arrays

[Brian Lavender <brian brie com>]

Turns out that my simplearray2.c did work! But when I printed out the
arrays, I forget to make the subscript so that it referenced the different
arrays, but instead just one!

See correction below

Now that recall you can pass an array directly, I won't be using this
function prototype to pass arguments!

void load_array( GArray *(*garray)[NUM_ARYS] );

I will check out the g_ptr_array!
