socket_option_name

enum class xtd::net::sockets::socket_option_name

strong

Defines configuration option names.

enum class socket_option_name

Header

#include <xtd/net/sockets/socket_option_name>

Namespace

xtd::net::sockets

Library

xtd.core

Remarks

The xtd::net::sockets::socket_option_name enumeration defines the name of each xtd::net::sockets::socket configuration option. Sockets can be configured with the xtd::net::sockets::socket::set_socket_option method.

Enumerator
debug	Record debugging information.
accept_connection	The socket is listening.
reuse_address	Allows the socket to be bound to an address that is already in use.
keep_alive	Use keep-alive.
dont_route	Do not route; send the packet directly to the interface addresses.
broadcast	Permit sending broadcast messages on the socket.
use_loopback	Bypass hardware when possible.
linger	Linger on close if unsent data is present.
out_of_band_inline	Receives out-of-band data in the normal data stream.
dont_linger	Close the socket gracefully without lingering.
exclusive_address_use	Enables a socket to be bound for exclusive access.
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.
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.
send_low_water	Specifies the low water mark for xtd::net::sockets::socket::send operations.
receive_low_water	Specifies the low water mark for xtd::net::sockets::socket::receive operations.
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.
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.
error	Gets the error status and clear.
type	Gets the socket type.
max_connections	Not supported; will throw a xtd::net::sockets::socket_exception exception if used.
ip_options	Specifies the IP options to be inserted into outgoing datagrams.
header_included	Indicates that the application provides the IP header for outgoing datagrams.
type_of_service	Change the IP header type of the service field.
ip_time_to_live	Sets the IP header Time-to-Live field.
multicast_interface	Sets the interface for outgoing multicast packets.
multicast_time_to_live	An IP multicast Time to Live.
multicast_loopback	An IP multicast loopback.
add_membership	Add an IP group membership.
drop_membership	Drop an IP group membership.
dont_fragment	Do not fragment IP datagrams.
add_source_membership	Join a source group.
drop_source_membership	Drop a source group.
block_source	Block data from a source.
unblock_source	Unblock a previously blocked source.
packet_information	Return information about received packets.
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.
ip_protection_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.
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.
no_delay	Disables the Nagle algorithm for send coalescing.
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.
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.
no_checksum	Send UDP datagrams with checksum set to zero.
checksum_coverage	Sets or get the UDP checksum coverage.
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.
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.
