Federico G. Schwindt : Improved client announcement

Module: ngircd.git Branch: master Commit: 8e60fac73b791129b69d20c9e5b02ee1e89f6eaa URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=8e60fac7… Author: Federico G. Schwindt <fgsch(a)lodoss.net> Date: Sun Aug 4 00:22:38 2013 +0100 Improved client announcement Move Announce_User() to client.c and rename it to Client_Announce(). Use this in cb_introduceClient() instead of duplicating the code. This fix the certificate fingerprint announcement for new clients.
