From e0807c430239d62d8dd7a25552e469aad8c3dd28 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Thu, 27 Apr 2023 15:39:48 +0200 Subject: mISDN: Use list_count_nodes() count_list_member() really looks the same as list_count_nodes(), so use the latter instead of hand writing it. The first one return an int and the other a size_t, but that should be fine. It is really unlikely that we get so many parties in a conference.
