No, wm->wregions[y][x] is a region.
  • wm->wregions is the beginning address of an array of region pointers. This array forms one dimension. Given that y is used as the index, one can visualize this array as denoting the vertical axis.
  • Each wm->wregions[y] element (where each is a pointer to another array of region's...) points to another singly-dimensioned array which can be visualized as representing the horizontal axis. Note the symbolism of x.
