* Server gewesen, so existiert eine entsprechende CONNECTION-Struktur.
*
* $Log: client.c,v $
+ * Revision 1.28 2002/01/11 23:50:40 alex
+ * - Hop-Count fuer den Server selber (0) wird korrekt initialisiert.
+ *
+ * Revision 1.27 2002/01/09 01:08:08 alex
+ * - wird ein Server abgemeldet, so wird anderen Server ein SQUIT geschickt.
+ *
+ * Revision 1.26 2002/01/07 23:42:12 alex
+ * - Es werden fuer alle Server eigene Token generiert,
+ * - QUIT von einem Server fuer einen User wird an andere Server geforwarded,
+ * - ebenso NICK-Befehle, die "fremde" User einfuehren.
+ *
+ * Revision 1.25 2002/01/07 15:31:00 alex
+ * - Bei Log-Meldungen ueber Clients wird nun immer die "Client Mask" verwendet.
+ *
+ * Revision 1.24 2002/01/06 15:18:14 alex
+ * - Loglevel und Meldungen nochmals geaendert. Level passen nun besser.
+ *
+ * Revision 1.23 2002/01/05 23:26:05 alex
+ * - Vorbereitungen fuer Ident-Abfragen in Client-Strukturen.
+ *
+ * Revision 1.22 2002/01/05 20:08:17 alex
+ * - neue Funktion Client_NextHop().
+ *
+ * Revision 1.21 2002/01/05 19:15:03 alex
+ * - Fehlerpruefung bei select() in der "Hauptschleife" korrigiert.
+ *
+ * Revision 1.20 2002/01/04 17:57:08 alex
+ * - Client_Destroy() an Server-Links angepasst.
+ *
* Revision 1.19 2002/01/04 01:21:22 alex
* - Client-Strukturen koennen von anderen Modulen nun nur noch ueber die
* enstprechenden (zum Teil neuen) Funktionen angesprochen werden.
