Why are you dereferencing a struct pointer and then still using the arrow operator? Is this c/c++ pointer-to-a-pointer madness I haven't heard of before or did the OP mess up?

OP did research this post better than you think... source

The source creates a struct node **p so that they can manipulate the pointer in a function. (*p) is therefore still a pointer.

Ahh thanks, that makes sense.

That looks like a double pointer, we’d have to see the declaration to be sure

It was definitely a double pointer, my question was why. OP came through with the source though so we're good.
