QUALAM NI CHANGING BREEDS WINDOWS
Most POSIX platforms and Windows are supposed to support If dualstack_ipv6 is true and the platform supports it the socket willīe able to accept both IPv4 and IPv6 connections, else it will raise Reuse_port dictates whether to set the SO_REUSEPORT socket option. (host, port)) and return the socket object.įamily should be either AF_INET or AF_INET6.īacklog is the queue size passed to socket.listen() when 0 create_server ( address, *, family = AF_INET, backlog = None, reuse_port = False, dualstack_ipv6 = False ) ¶Ĭonvenience function which creates a TCP socket bound to address (a 2-tuple Raises an auditing event socket._new_ with arguments self, family, type, protocol.Ĭhanged in version 3.2: source_address was added. The newly created socket is non-inheritable. This may help close a detached socket using omfd(), fileno will return the same socket and not aĭuplicate. Of socket.getpeername() but not the actual OS resource. This only affects how Python represents e.g. Overruled by calling the function with explicit family, type, or protoĪrguments. If fileno is specified, the values for family, type, and proto areĪuto-detected from the specified file descriptor.
Should be one of CAN_RAW, CAN_BCM, CAN_ISOTP or Or in the case where the address family is AF_CAN the protocol The protocol number is usually zero and may be omitted The socket type should be SOCK_STREAM (theĭefault), SOCK_DGRAM, SOCK_RAW or perhaps one of the other The address family should be AF_INET (the default), socket ( family = AF_INET, type = SOCK_STREAM, proto = 0, fileno = None ) ¶Ĭreate a new socket using the given address family, socket type and protocol The following functions all create socket objects. The tuple can be used if IDĪnd unit number of the kernel control are known or if a registered ID is Kernel control using a dynamically-assigned ID. (PGN), and an 8-bit integer representing the address.Ī string or a tuple (id, unit) is used for the SYSPROTO_CONTROL Where additional parameters are 64-bit unsigned integer representing theĮCU name, a 32-bit unsigned integer representing the Parameter Group Number Where both additional parameters are unsigned long integer that represent aĬAN_J1939 protocol require a tuple (interface, name, pgn, addr) The network interface name '' can be used to receive packetsįrom all network interfaces of this family.ĬAN_ISOTP protocol require a tuple (interface, rx_addr, tx_addr) Where interface is a string representing a network interface name like If addr_type is TIPC_ADDR_ID, then v1 is the node, v2 is theĪ tuple (interface, ) is used for the AF_CAN address family, Is the lower port number, and v3 is the upper port number. If addr_type is TIPC_ADDR_NAMESEQ, then v1 is the server type, v2 If addr_type is TIPC_ADDR_NAME, then v1 is the server type, v2 is Scope is one of TIPC_ZONE_SCOPE, TIPC_CLUSTER_SCOPE, and
(addr_type, v1, v2, v3 ), where:Īddr_type is one of TIPC_ADDR_NAMESEQ, TIPC_ADDR_NAME, Tuple, and the fields depend on the address type. TIPC is an open, non-IP based networked protocol designedįor use in clustered computer environments. Linux-only support for TIPC is available using the AF_TIPCĪddress family. This information is superfluous and mayĪF_NETLINK sockets are represented as pairs (pid, groups). Note, however, omission of scope_id can cause problemsĬhanged in version 3.7: For multicast addresses (with scope_id meaningful) address may not contain Socket module methods, flowinfo and scope_id can be omitted just forīackward compatibility.
Therefore, you may want to avoid these if you intend to support IPv6 with yourįor AF_INET6 address family, a four-tuple (host, port, flowinfo, scope_id) is used, where flowinfo and scope_id represent the sin6_flowinfoĪnd sin6_scope_id members in struct sockaddr_in6 in C. This behavior is not compatible with IPv6, Notation like '' or an IPv4 address like '100.50.200.5',įor IPv4 addresses, two special forms are accepted instead of a hostĪddress: '' represents INADDR_ANY, which is used to bind to all Where host is a string representing either a hostname in internet domain Changed in version 3.5: Writable bytes-like object is now accepted.Ī pair (host, port) is used for the AF_INET address family,
