IROAsyncInterfaceEx

Could someone give me some heads up on this interface IROAsyncInterfaceEx?

What is the utility of it?

Also - where can I find a sample project illustrating EventSink (callback)?

Thank you.

Hi,

this interface is the ancestor for _AsyncEx interfaces.
See example of it usage in the Phone Photo Server sample

See any chat sample, like SuperTCP Channel Chat or SuperHTTP Chat
