##### 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.

##### Data Members

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

The `basic_seq_packet_socket` class template provides asynchronous and blocking sequenced packet socket functionality.

##### Thread Safety

Distinct objects: Safe.

Shared objects: Unsafe.

Synchronous `send`, `receive`, `connect`, and `shutdown` operations are thread safe with respect to each other, if the underlying operating system calls are also thread safe. This means that it is permitted to perform concurrent calls to these synchronous operations on a single socket object. Other synchronous operations, such as `open` or `close`, are not thread safe.
