GlobalConfig.ConnectionReadyForSend

Description

Defines the callback delegate which you can use to get a notification when a connection is ready to send data.

The callback will be only be called if you specifically indicate that you want this notification, by calling NetworkTransport.NotifyWhenConnectionReadyForSend.

This callback will be called from the IO thread. If you execute a long operation from this callback it will affect your IO operation performance, therefore you should return from these operations as soon as possible.
