|

|
|
* Der Begriff "Client" ist in diesem Fall evtl. etwas verwirrend: Clients sind
|
|
|
|
* alle Verbindungen, die im gesamten(!) IRC-Netzwerk bekannt sind. Das sind IRC-
|
|
|
|
* Clients (User), andere Server und IRC-Services.
|
|
|
|
* Ueber welchen IRC-Server die Verbindung nun tatsaechlich in das Netzwerk her-
|
|
|
|
* gestellt wurde, muss der jeweiligen Struktur entnommen werden. Ist es dieser
|
|
|
|
* Server gewesen, so existiert eine entsprechende CONNECTION-Struktur.
