Subject: Completely remove need for memset.
X-Git-Tag: v2.0.23~7819
X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=a47ea856edfbd043d0295787fe7e1262fb8646a5;p=user%2Fhenk%2Fcode%2Finspircd.git

Completely remove need for memset.
When we uniq_id++, we can wrap to 0 theoretically after 4 billion output messages, HOWEVER, when we do, 0 will be a valid comparison within the array :p
