ListForeachPtrReverseDescription
Iterate over each element var (as a pointer) of the given list l in reverse order. The variable var is declared and defined by this macro as a pointer to the list’s data type. Iteration happens in reverse, starting from the tail of the list and continuing through the prev pointers until the head is reached. The variable var will point to the data associated with each list node.
