int(* parent_cmp()¶

Compare two structs.h::gnrc_rpl_parent_t.

Compares two parents based on the rank calculated by the objective function. This function is used to determine the parent list order. The parents are ordered from the preferred parent to the least preferred parent.

Parameters

parent1:	First parent to compare.
parent2:	Second parent to compare.

Return values

Zero if the parents are of equal preference.
Positive, if the second parent is preferred.
Negative, if the first parent is preferred.
