A move accept handler must meet the requirements for a handler.
A value h
of a move accept handler class should work correctly
in the expression h(ec, s)
, where ec
is an lvalue
of type const error_code
and s
is an lvalue of
the nested type Protocol::socket
for the type Protocol
of the socket class template.
A free function as a move accept handler:
void accept_handler( const asio::error_code& ec, asio::ip::tcp::socket s) { ... }
A move accept handler function object:
struct accept_handler { ... void operator()( const asio::error_code& ec, asio::ip::tcp::socket s) { ... } ... };
A lambda as a move accept handler:
acceptor.async_accept(..., [](const asio::error_code& ec, asio::ip::tcp::socket s) { ... });
A non-static class member function adapted to a move accept handler using
std::bind()
:
void my_class::accept_handler( const asio::error_code& ec, asio::ip::tcp::socket socket) { ... } ... asio::async_accept(..., std::bind(&my_class::accept_handler, this, std::placeholders::_1, std::placeholders::_2));
