disconnect() calls a sysDisconnectEvent of it's own

[Roland Goldberg]

Sample Code:

function doubleEcho()
  cecho("\n<black:yellow>This will echo twice, but only if currently connected to the MUD when disconenct() is called")
end

registerAnonymousEventHandler("sysDisconnectionEvent","doubleEcho")

disconnect()

Explanation:

sysDisconnectEvent is designed to let you know that the connection to the MUD has been terminated. However, regardless of whether there is a connection to the MUD, calling the disconnect() function raises sysDisconnectEvent. When connected to a MUD, this results in sysDisconnectEvent being called twice if you manually run a disconnect(). If the MUD disconnects you on the other hand, you only get one sysDisconnectEvent, as proper.

Usually this is no problem. However, sometimes a function that is registered to sysDisconnectEvent will have issues if it is run twice. Other times you may not want said function to run unless already connected to the MUD when disconnect() is called.
