2017-08-10T07:18:30 Sascha2018Hallo.

Wie gesagt... Habe alle Verbindungen ( Sockets ) in einem

eine Nachricht schicken kann.
Blos IPC::Shareable scheint nicht davon begeistert zu sein.

2017-08-12T15:42:29 Sascha2018Durch $pm->start wird fork() aufgerufen.
Über $pm->finish(0, { # vars }) werden die Variablen des Kindprozesses am Ende des Durchlaufs aktualisiert.

2017-08-13T08:36:09 Sascha2018%clients wird nach Ende des Childprozess im Hauptprozess geupdatet.
$lkup{$ident} wird im Hauptprozess dem Socket vom accept() zugewiesen und am Ende des Kindprozess $clients{$ident}->{socket} in der run_on_fish subroutine durch die delete Funktion zugewiesen.
