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.
implementation_type	The underlying implementation type of I/O 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.
native_type	(Deprecated: Use native_handle_type.) The native representation of a socket.
non_blocking_io	(Deprecated: Use non_blocking().) IO control command to set the blocking mode of the socket.
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.
service_type	The type of the service that will be used to provide I/O operations.
shutdown_type	Different ways a socket may be shutdown.
