From 002a51d7319a5d24fede88eaae5c155b3c2fd6aa Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Wed, 30 Oct 2019 04:37:47 +0100 Subject: add osmo_sockaddr_str_cmp() Currently planned user: for Distributed GSM in osmo-hlr: setting per-MSC service addresses in VTY: replace/remove existing entries. osmo_sockaddr_str_cmp() is useful to catch identical resulting IP addresses, regardless of differing strings (e.g. '0::' and '::' are equal but differ in strings).
