You need to allocate some memory for the sprites first:

	sprite[0]->bitmap = create_bitmap(16, 16);

I would probably use a function like:

	BITMAP *clone_bitmap(BITMAP *src)
	{
	    BITMAP *b;
	    b = create_bitmap_ex(bitmap_color_depth(src), src->w, src->h);
	    if (b) 
	    	blit(src, b, 0, 0, 0, 0, src->w, src->h);
	    return b;
	}
	
But you might as well use the graphics straight from the datafile structure.

	sprite[0]->bitmap = file[0].dat;
