This function is used to asynchronously write data from the stream. The function call always returns immediately.

One or more data buffers to be written to the stream. Although the buffers object may be copied as necessary, ownership of the underlying memory blocks is retained by the caller, which must guarantee that they remain valid until the handler is called. |

The completion handler to invoke when the operation completes. The implementation takes ownership of the handler by performing a decay-copy. The equivalent function signature of the handler must be: void handler( error_code const & error, // result of operation std::size_t bytes_transferred // number of bytes transferred );
If the handler has an associated immediate executor, an immediate
completion will be dispatched to it. Otherwise, the handler will
not be invoked from within this function. Invocation of the handler
will be performed by dispatching to the immediate executor. If
no immediate executor is specified, this is equivalent to using
