I have a question about C ++ boost :: asio and std :: async

Question

I know that both are designed asynchronously.

What I'm curious about is the function callback when creating a thread using the above two.

Is it possible for a single thread to write and read asynchronously?

Answer 1

Yes. In fact I have many examples of that on this site.

I wrote one yesterday that starts out with true single-threading:

• How to pass a boost asio tcp socket to a thread for sending heartbeat to client or server

Note that you can easily also do multi-client servers on a single thread:

• Boost.Asio: Is it a good thing to use a `io_service` per connection/socket?
• With a twist (because it wants to synchronize writing to all clients) Thread-safety when accessing data from N-theads in context of an async TCP-server

There must be many more, but these are the first hits I see.
