websocket::async_teardown (2 of 2 overloads)

Start tearing down a net::ip::tcp::socket.

Synopsis

Defined in header <boost/beast/websocket/teardown.hpp>

template<
    class Protocol,
    class Executor,
    class TeardownHandler>
void
async_teardown(
    role_type role,
    net::basic_stream_socket< Protocol, Executor >& socket,
    TeardownHandler&& handler);

This begins tearing down a connection asynchronously. The implementation will call the overload of this function based on the Stream parameter used to consruct the socket. When Stream is a user defined type, and not a net::ip::tcp::socket or any net::ssl::stream, callers are responsible for providing a suitable overload of this function.

Remarks

This function serves as a customization point and is not intended to be called directly.

Parameters

Name	Description
`role`	The role of the local endpoint
`socket`	The socket to tear down.
`handler`	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 ); 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 in a manner equivalent to using `net::post`.

Name

Description

role

The role of the local endpoint

socket

The socket to tear down.

handler

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
);

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 in a manner equivalent to using net::post.

Per-Operation Cancellation

This asynchronous operation supports cancellation for the following net::cancellation_type values:

net::cancellation_type::terminal
net::cancellation_type::partial
net::cancellation_type::total

if they are also supported by the socket's async_wait operation.
