  public socket_base
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.

lowest_layer_type

A basic_socket is always the lowest layer.

message_flags

Bitmask type for flags that can be passed to send and receive operations.

native_handle_type

The native representation of a socket.

out_of_band_inline

Socket option for putting received out-of-band data inline.

protocol_type

The protocol type.

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

Member Functions

Name

Description

assign

Assign an existing native socket to the socket.

async_connect

Start an asynchronous connect.

async_wait

at_mark

Determine whether the socket is at the out-of-band data mark.

available

Determine the number of bytes available for reading.

basic_socket

Construct a basic_socket without opening it.

bind

Bind the socket to the given local endpoint.

cancel

Cancel all asynchronous operations associated with the socket.

close

Close the socket.

connect

Connect the socket to the specified endpoint.

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 socket.

io_control

Perform an IO control command on the socket.

is_open

Sets the non-blocking mode of the native socket implementation.

non_blocking

Gets the non-blocking mode of the socket.

Sets the non-blocking mode of the socket.

open

Open the socket using the specified protocol.

operator=

Move-assign a basic_socket from another.

Move-assign a basic_socket from a socket of another protocol type.

release

Release ownership of the underlying native socket.

remote_endpoint

Get the remote endpoint of the socket.

set_option

Set an option on the socket.

shutdown

Protected Member Functions

Name

Description

~basic_socket

Protected destructor to prevent deletion through this type.

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 class template provides functionality that is common to both stream-oriented and datagram-oriented sockets.
