| 52 | based on the `Stream` parameter used to consruct the socket. |
| 53 | When `Stream` is a user defined type, and not a |

| 67 | @param handler The completion handler to invoke when the operation |
| 68 | completes. The implementation takes ownership of the handler by |
| 69 | performing a decay-copy. The equivalent function signature of |
| 70 | the handler must be: |
| 71 | @code |
| 72 | void handler( |
| 73 | error_code const& error // result of operation |
| 74 | ); |
| 75 | @endcode |
| 76 | If the handler has an associated immediate executor, |
| 77 | an immediate completion will be dispatched to it. |
| 78 | Otherwise, the handler will not be invoked from within |
| 79 | this function. Invocation of the handler will be performed in a |
| 80 | manner equivalent to using `net::post`. |
| 81 | |
| 82 | @par Per-Operation Cancellation |
| 83 | |
| 84 | This asynchronous operation supports cancellation for the following |
| 85 | net::cancellation_type values: |
| 86 | |
| 87 | @li @c net::cancellation_type::terminal |
| 88 | @li @c net::cancellation_type::partial |
| 89 | @li @c net::cancellation_type::total |
| 90 | |
| 91 | if they are also supported by the socket's @c async_teardown |
| 92 | and @c async_shutdown operation. |
