Module: ngircd.git Branch: master Commit: 1dc93286a0d5b80259604b4f25021fcc5a730b5b URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=1dc93286a... Author: Alexander Barton <alex@barton.de> Date: Mon Aug 26 22:54:00 2013 +0200 Save client IP address text for "WebIRC" users This patch introduces a new field in the CLIENT structure, "ipa_text", which points to an optional textual representation of the client IP address (or NULL) which can be used to store the "real" IP address information of a client using the "WEBIRC" protocol. Without this patch, ngIRCd ignored the <ip-address> paramater ... In addition, the functions Client_SetIPAText() and Client_IPAText() have been introduced to set and get the textual representation of the client IP address. Client_IPAText() can be used even when no "IP address text" has been set before, it then returns the real IP address of the connection.
