The socket is listening.

Add an IP group membership.

Join a source group.

Block data from a source.

Permit sending broadcast messages on the socket.

Use urgent data as defined in RFC-1222. This option can be set only once; after it is set, it cannot be turned off.

Set or get the UDP checksum coverage.

Record debugging information.

Do not fragment IP datagrams.

Close the socket gracefully without lingering.

Do not route; send the packet directly to the interface addresses.

Drop an IP group membership.

Drop a source group.

Get the error status and clear.

Enables a socket to be bound for exclusive access.

Use expedited data as defined in RFC-1222. This option can be set only once; after it is set, it cannot be turned off.

Indicates that the application provides the IP header for outgoing datagrams.

Specifies the maximum number of router hops for an Internet Protocol version 6 (IPv6) packet. This is similar to Time to Live (TTL) for Internet Protocol version 4.

Specifies the IP options to be inserted into outgoing datagrams.

Set the IP header Time-to-Live field.

Use keep-alives.

Linger on close if unsent data is present.

Not supported; will throw a System.Net.Sockets.SocketException if used.

Set the interface for outgoing multicast packets.

An IP multicast loopback.

An IP multicast Time to Live.

Send UDP datagrams with checksum set to zero.

Disables the Nagle algorithm for send coalescing.

Receives out-of-band data in the normal data stream.

Return information about received packets.

Specifies the total per-socket buffer space reserved for receives. This is unrelated to the maximum message size or the size of a TCP window.

Specifies the low water mark for erload:System.Net.Sockets.Socket.Receive operations.

Receive a time-out. This option applies only to synchronous methods; it has no effect on asynchronous methods such as the Socket.BeginSend(Byte[], int, int, SocketFlags, AsyncCallback, object) method.

Allows the socket to be bound to an address that is already in use.

Specifies the total per-socket buffer space reserved for sends. This is unrelated to the maximum message size or the size of a TCP window.

Specifies the low water mark for erload:System.Net.Sockets.Socket.Send operations.

Send a time-out. This option applies only to synchronous methods; it has no effect on asynchronous methods such as the Socket.BeginSend(Byte[], int, int, SocketFlags, AsyncCallback, object) method.

Get the socket type.

Change the IP header type of the service field.

Unblock a previously blocked source.

Updates an accepted socket's properties by using those of an existing socket. This is equivalent to using the Winsock2 SO_UPDATE_ACCEPT_CONTEXT socket option and is supported only on connection-oriented sockets.

Updates a connected socket's properties by using those of an existing socket. This is equivalent to using the Winsock2 SO_UPDATE_CONNECT_CONTEXT socket option and is supported only on connection-oriented sockets.

Bypass hardware when possible.
