IO-Socket-INET6 is deprecated.\n\nIO-Socket-INET6 was now succeeded by Paul Evans' IO::Socket::IP . Please convert old code from\nIO-Socket-INET6 to IO-Socket-IP.\n", "subsections": [] }, "DESCRIPTION": { "content": "\"IO::Socket::INET6\" provides an object interface to creating and using sockets in either AFINET\nor AFINET6 domains. It is built upon the IO::Socket interface and inherits all the methods\ndefined by IO::Socket.\n", "subsections": [] }, "CONSTRUCTOR": { "content": "new ( [ARGS] )\nCreates an \"IO::Socket::INET6\" object, which is a reference to a newly created symbol (see\nthe \"Symbol\" package). \"new\" optionally takes arguments, these arguments are in key-value\npairs.\n\nIn addition to the key-value pairs accepted by IO::Socket, \"IO::Socket::INET6\" provides.\n\nDomain Address family AFINET | AFINET6 | AFUNSPEC (default)\nPeerAddr Remote host address [:]\nPeerHost Synonym for PeerAddr\nPeerPort Remote port or service [()] | \nPeerFlow Remote flow information\nPeerScope Remote address scope\nLocalAddr Local host bind address hostname[:port]\nLocalHost Synonym for LocalAddr\nLocalPort Local host bind port [()] | \nLocalFlow Local host flow information\nLocalScope Local host address scope\nProto Protocol name (or number) \"tcp\" | \"udp\" | ...\nType Socket type SOCKSTREAM | SOCKDGRAM | ...\nListen Queue size for listen\nReuseAddr Set SOREUSEADDR before binding\nReuse Set SOREUSEADDR before binding (deprecated, prefer ReuseAddr)\nReusePort Set SOREUSEPORT before binding\nBroadcast Set SOBROADCAST before binding\nTimeout Timeout value for various operations\nMultiHomed Try all addresses for multi-homed hosts\nBlocking Determine if connection will be blocking mode\n\nIf \"Listen\" is defined then a listen socket is created, else if the socket type, which is\nderived from the protocol, is SOCKSTREAM then connect() is called.\n\nAlthough it is not illegal, the use of \"MultiHomed\" on a socket which is in non-blocking\nmode is of little use. This is because the first connect will never fail with a timeout as\nthe connect call will not block.\n\nThe \"PeerAddr\" can be a hostname, the IPv6-address on the \"2001:800:40:2a05::10\" form , or\nthe IPv4-address on the \"213.34.234.245\" form. The \"PeerPort\" can be a number or a symbolic\nservice name. The service name might be followed by a number in parenthesis which is used if\nthe service is not known by the system. The \"PeerPort\" specification can also be embedded in\nthe \"PeerAddr\" by preceding it with a \":\", and closing the IPv6 address on brackets \"[]\" if\nnecessary: \"124.678.12.34:23\",\"[2a05:345f::10]:23\",\"any.server.com:23\".\n\nIf \"Domain\" is not given, AFUNSPEC is assumed, that is, both AFINET and AFINET6 will be\nboth considered when resolving DNS names. AFINET6 has priority. If you guess you are in\ntrouble not reaching the peer,(the service is not available via AFINET6 but AFINET) you\ncan either try Multihomed (try any address/family until reach) or concrete your address\n\"family\" (AFINET, AFINET6).\n\nIf \"Proto\" is not given and you specify a symbolic \"PeerPort\" port, then the constructor\nwill try to derive \"Proto\" from the service name. As a last resort \"Proto\" \"tcp\" is assumed.\nThe \"Type\" parameter will be deduced from \"Proto\" if not specified.\n\nIf the constructor is only passed a single argument, it is assumed to be a \"PeerAddr\"\nspecification.\n\nIf \"Blocking\" is set to 0, the connection will be in nonblocking mode. If not specified it\ndefaults to 1 (blocking mode).\n\nExamples:\n\n$sock = IO::Socket::INET6->new(PeerAddr => 'www.perl.org',\nPeerPort => 'http(80)',\nProto => 'tcp');\n\nSuppose either you have no IPv6 connectivity or www.perl.org has no http service on IPv6.\nThen,\n\n(Trying all address/families until reach)\n\n$sock = IO::Socket::INET6->new(PeerAddr => 'www.perl.org',\nPeerPort => 'http(80)',\nMultihomed => 1 ,\nProto => 'tcp');\n\n(Concrete to IPv4 protocol)\n\n$sock = IO::Socket::INET6->new(PeerAddr => 'www.perl.org',\nPeerPort => 'http(80)',\nDomain => AFINET ,\nProto => 'tcp');\n\n\n$sock = IO::Socket::INET6->new(PeerAddr => 'localhost:smtp(25)');\n\n$sock = IO::Socket::INET6->new(Listen => 5,\nLocalAddr => 'localhost',\nLocalPort => 9000,\nProto => 'tcp');\n\n$sock = IO::Socket::INET6->new('[::1]:25');\n\n$sock = IO::Socket::INET6->new(PeerPort => 9999,\nPeerAddr => Socket6::inetntop(AFINET6,in6addrbroadcast),\nProto => udp,\nLocalAddr => 'localhost',\nBroadcast => 1 )\nor die \"Can't bind : $@\\n\";\n\nNOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE\n\nAs of VERSION 1.18 all IO::Socket objects have autoflush turned on by default.
