| This is a example of showing multiple clients share one connection. |
| |
| There are one server(Echo) and three clients(Client and Sender, Client has two instances). |
| 1. All of the three clients connect to the same RPC interface that the server provides. |
| 2. When the server emits a event, all of the clients will receive it. |
| 3. The dataport is shared among the server and the clients. Note that, the clients can see |
| each other's data in the dataport. |
| |
| Those connections run in separate threads which could cause race conditions potentially. |
| It is the user's responsibility to apply proper locking mechanism if the underlying |
| functions are not reentrant. |
