ip::tcp::acceptor

The TCP acceptor type.

typedef basic_socket_acceptor< tcp > acceptor;

Types

Name	Description
broadcast	Socket option to permit sending of broadcast messages.
bytes_readable	IO control command to get the amount of data that can be read without blocking.
debug	Socket option to enable socket-level debugging.
do_not_route	Socket option to prevent routing, use local interfaces only.
enable_connection_aborted	Socket option to report aborted connections on accept.
endpoint_type	The endpoint type.
executor_type	The type of the executor associated with the object.
keep_alive	Socket option to send keep-alives.
linger	Socket option to specify whether the socket lingers on close if unsent data is present.
message_flags	Bitmask type for flags that can be passed to send and receive operations.
native_handle_type	The native representation of an acceptor.
out_of_band_inline	Socket option for putting received out-of-band data inline.
protocol_type	The protocol type.
receive_buffer_size	Socket option for the receive buffer size of a socket.
receive_low_watermark	Socket option for the receive low watermark.
reuse_address	Socket option to allow the socket to be bound to an address that is already in use.
send_buffer_size	Socket option for the send buffer size of a socket.
send_low_watermark	Socket option for the send low watermark.
shutdown_type	Different ways a socket may be shutdown.
wait_type	Wait types.

Member Functions

Name	Description
accept	Accept a new connection. — Accept a new connection and obtain the endpoint of the peer.
assign	Assigns an existing native acceptor to the acceptor.
async_accept	Start an asynchronous accept.
async_wait	Asynchronously wait for the acceptor to become ready to read, ready to write, or to have pending error conditions.
basic_socket_acceptor	Construct an acceptor without opening it. — Construct an open acceptor. — Construct an acceptor opened on the given endpoint. — Construct a basic_socket_acceptor on an existing native acceptor. — Move-construct a basic_socket_acceptor from another. — Move-construct a basic_socket_acceptor from an acceptor of another protocol type.
bind	Bind the acceptor to the given local endpoint.
cancel	Cancel all asynchronous operations associated with the acceptor.
close	Close the acceptor.
get_executor	Get the executor associated with the object.
get_io_context	(Deprecated: Use get_executor().) Get the io_context associated with the object.
get_io_service	(Deprecated: Use get_executor().) Get the io_context associated with the object.
get_option	Get an option from the acceptor.
io_control	Perform an IO control command on the acceptor.
is_open	Determine whether the acceptor is open.
listen	Place the acceptor into the state where it will listen for new connections.
local_endpoint	Get the local endpoint of the acceptor.
native_handle	Get the native acceptor representation.
native_non_blocking	Gets the non-blocking mode of the native acceptor implementation. — Sets the non-blocking mode of the native acceptor implementation.
non_blocking	Gets the non-blocking mode of the acceptor. — Sets the non-blocking mode of the acceptor.
open	Open the acceptor using the specified protocol.
operator=	Move-assign a basic_socket_acceptor from another. — Move-assign a basic_socket_acceptor from an acceptor of another protocol type.
release	Release ownership of the underlying native acceptor.
set_option	Set an option on the acceptor.
wait	Wait for the acceptor to become ready to read, ready to write, or to have pending error conditions.
~basic_socket_acceptor	Destroys the acceptor.

Data Members

Name	Description
max_connections	(Deprecated: Use max_listen_connections.) The maximum length of the queue of pending incoming connections.
max_listen_connections	The maximum length of the queue of pending incoming connections.
message_do_not_route	Specify that the data should not be subject to routing.
message_end_of_record	Specifies that the data marks the end of a record.
message_out_of_band	Process out-of-band data.
message_peek	Peek at incoming data without removing it from the input queue.

The basic_socket_acceptor class template is used for accepting new socket connections.

Thread Safety

Distinct objects: Safe.

Shared objects: Unsafe.

Example

Opening a socket acceptor with the SO_REUSEADDR option enabled:

asio::ip::tcp::acceptor acceptor(io_context);
asio::ip::tcp::endpoint endpoint(asio::ip::tcp::v4(), port);
acceptor.open(endpoint.protocol());
acceptor.set_option(asio::ip::tcp::acceptor::reuse_address(true));
acceptor.bind(endpoint);
acceptor.listen();
