Variables
constexpr int32_t	SOCKET_OPTION_NAME_DEBUG
	Record debugging information.
constexpr int32_t	SOCKET_OPTION_NAME_ACCEPT_CONNECTION
	The socket is listening.
constexpr int32_t	SOCKET_OPTION_NAME_REUSE_ADDRESS

constexpr int32_t	SOCKET_OPTION_NAME_KEEP_ALIVE
	Use keep-alive.
constexpr int32_t	SOCKET_OPTION_NAME_DONT_ROUTE
	Do not route; send the packet directly to the interface addresses.
constexpr int32_t	SOCKET_OPTION_NAME_BROADCAST
	Permit sending broadcast messages on the socket.
constexpr int32_t	SOCKET_OPTION_NAME_USE_LOOPBACK
	Bypass hardware when possible.
constexpr int32_t	SOCKET_OPTION_NAME_LINGER
	Linger on close if unsent data is present.
constexpr int32_t	SOCKET_OPTION_NAME_OUT_OF_BAND_INLINE
	Receives out-of-band data in the normal data stream.
constexpr int32_t	SOCKET_OPTION_NAME_DONT_LINGER
	Close the socket gracefully without lingering.
constexpr int32_t	SOCKET_OPTION_NAME_EXCLUSIVE_ADDRESS_USE
	Enables a socket to be bound for exclusive access.
constexpr int32_t	SOCKET_OPTION_NAME_SEND_BUFFER
	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.
constexpr int32_t	SOCKET_OPTION_NAME_RECEIVE_BUFFER
	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.
constexpr int32_t	SOCKET_OPTION_NAME_SEND_LOW_WATER
	Specifies the low water mark for xtd::net::sockets::socket::send operations.
constexpr int32_t	SOCKET_OPTION_NAME_RECEIVE_LOW_WATER
	Specifies the low water mark for xtd::net::sockets::socket::receive operations.
constexpr int32_t	SOCKET_OPTION_NAME_SEND_TIMEOUT
	Send a time-out. This option applies only to synchronous methods; it has no effect on asynchronous methods such as the xtd::net::sockets::socket::begin_send method.
constexpr int32_t	SOCKET_OPTION_NAME_RECEIVE_TIMEOUT
	Receive a time-out. This option applies only to synchronous methods; it has no effect on asynchronous methods such as the xtd::net::sockets::socket::begin_send method.
constexpr int32_t	SOCKET_OPTION_NAME_ERROR
	Gets the error status and clear.
constexpr int32_t	SOCKET_OPTION_NAME_TYPE
	Gets the socket type.
constexpr int32_t	SOCKET_OPTION_NAME_MAX_CONNECTION
	Not supported; will throw a xtd::net::sockets::socket_exception exception if used.
constexpr int32_t	SOCKET_OPTION_NAME_IP_OPTIONS
	Specifies the IP options to be inserted into outgoing datagrams.
constexpr int32_t	SOCKET_OPTION_NAME_HEADER_INCLUDED
	Indicates that the application provides the IP header for outgoing datagrams.
constexpr int32_t	SOCKET_OPTION_NAME_TYPE_OF_SERVICE
	Change the IP header type of the service field.
constexpr int32_t	SOCKET_OPTION_NAME_IP_TIME_TO_LIVE
	Sets the IP header Time-to-Live field.
constexpr int32_t	SOCKET_OPTION_NAME_MULTICAST_INTERFACE
	Sets the interface for outgoing multicast packets.
constexpr int32_t	SOCKET_OPTION_NAME_MULTICAST_TIME_TO_LIVE
	An IP multicast Time to Live.
constexpr int32_t	SOCKET_OPTION_NAME_MULTICAST_LOOPBACK
	An IP multicast loopback.
constexpr int32_t	SOCKET_OPTION_NAME_ADD_MEMBERSHIP
	Add an IP group membership.
constexpr int32_t	SOCKET_OPTION_NAME_DROP_MEMBERSHIP
	Drop an IP group membership.
constexpr int32_t	SOCKET_OPTION_NAME_DONT_FRAGMENT
	Do not fragment IP datagrams.
constexpr int32_t	SOCKET_OPTION_NAME_ADD_SOURCE_MEMBERSHIP
	Join a source group.
constexpr int32_t	SOCKET_OPTION_NAME_DROP_SOURCE_MEMBERSHIP
	Drop a source group.
constexpr int32_t	SOCKET_OPTION_NAME_BLOCK_SOURCE
	Block data from a source.
constexpr int32_t	SOCKET_OPTION_NAME_UNBLOCK_SOURCE
	Unblock a previously blocked source.
constexpr int32_t	SOCKET_OPTION_NAME_PACKET_INFORMATION
	Return information about received packets.
constexpr int32_t	SOCKET_OPTION_NAME_HOP_LIMIT
	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.
constexpr int32_t	SOCKET_OPTION_NAME_IP_PROTECT_LEVEL
	Enables restriction of a IPv6 socket to a specified scope, such as addresses with the same link local or site local prefix.This socket option enables applications to place access restrictions on IPv6 sockets. Such restrictions enable an application running on a private LAN to simply and robustly harden itself against external attacks. This socket option widens or narrows the scope of a listening socket, enabling unrestricted access from public and private users when appropriate, or restricting access only to the same site, as required. This socket option has defined protection levels specified in the xtd::net::sockets::ip_protection_level enumeration.
constexpr int32_t	SOCKET_OPTION_NAME_IP_V6_ONLY
	Indicates if a socket created for the AF_INET6 address family is restricted to IPv6 communications only. Sockets created for the AF_INET6 address family may be used for both IPv6 and IPv4 communications. Some applications may want to restrict their use of a socket created for the AF_INET6 address family to IPv6 communications only. When this value is non-zero (the default on Windows), a socket created for the AF_INET6 address family can be used to send and receive IPv6 packets only. When this value is zero, a socket created for the AF_INET6 address family can be used to send and receive packets to and from an IPv6 address or an IPv4 address. Note that the ability to interact with an IPv4 address requires the use of IPv4 mapped addresses. This socket option is supported on Windows Vista or later.
constexpr int32_t	SOCKET_OPTION_NAME_NO_DELAY
	Disables the Nagle algorithm for send coalescing.
constexpr int32_t	SOCKET_OPTION_NAME_BSD_URGENT
	Use urgent data as defined in RFC-1222. This option can be set only once; after it is set, it cannot be turned off.
constexpr int32_t	SOCKET_OPTION_NAME_EXPEDITED
	Use expedited data as defined in RFC-1222. This option can be set only once; after it is set, it cannot be turned off.
constexpr int32_t	SOCKET_OPTION_NAME_NO_CHECKSUM
	Send UDP datagrams with checksum set to zero.
constexpr int32_t	SOCKET_OPTION_NAME_CHECKSUM_COVERAGE
	Sets or get the UDP checksum coverage.
constexpr int32_t	SOCKET_OPTION_NAME_UPDATE_ACCEPT_CONTEXT
	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.
constexpr int32_t	SOCKET_OPTION_NAME_UPDATE_CONNECT_CONTEXT
	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.
