typedef basic_datagram_socket< udp > socket;
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

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

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
