Hi, I modified a little the echo server example and to build up a simple tcp server; basically what I do is:

- Start the server in a thread

- When a session is created I start  async read

- If my session receive a signal I  write a data with async write function

- Handle data written then start again async read ( otherwise the connection should be closed )

I have some specific functions which prepare packets and then invoke the write method

I would like to avoid static allocation of my buffer instead of dynamic one; for doing that I supposed to use shared_array<T>

I can’t do that because the boost::asio::buffer, required by the write method, doesn’t seem to accept smart pointer.

So my questions are:

- Is there a common pattern to follow for preparing data and delete them after the delivery ?

- Is it possible to use smart pointers with async_write ?

- Is the async_write executed in another thread ? should I have concurrency problems if I would use an unique output buffer and clear it on the handle_write callback ?

Thanks
