Good idea, a bit of nit picking ..
does ix_ has a special meaning ? otherwise x,y would be sufficient.
ix typical stands for index, but I think just x and y are fine too.
From the code below i can see: y=x+1 Perhaps that can be used.
So are you proposing to use two arguments instead of three?
re_sort_routes(nr_node, 0);
kernel.h has a swap() macro. so you can
swap(nr_node->routes[x],nr_node->routes[y]);
Nice, I will use that macro.
hope that helps,
Definitely. I appreciate your comments.
Thanks!
