- * Addrinfo.new(sockaddr, family) => addrinfo
- * Addrinfo.new(sockaddr, family, socktype) => addrinfo
- * Addrinfo.new(sockaddr, family, socktype, protocol) => addrinfo
- *
- * returns a new instance of Addrinfo.
- * The instance contains sockaddr, family, socktype, protocol.
- * sockaddr means struct sockaddr which can be used for connect(2), etc.
- * family, socktype and protocol are integers which is used for arguments of socket(2).
- *
- * sockaddr is specified as an array or a string.
- * The array should be compatible to the value of IPSocket#addr or UNIXSocket#addr.
- * The string should be struct sockaddr as generated by
- * Socket.sockaddr_in or Socket.unpack_sockaddr_un.
- *
- * sockaddr examples:
- * - ["AF_INET", 46102, "localhost.localdomain", "127.0.0.1"]
- * - ["AF_INET6", 42304, "ip6-localhost", "::1"]
- * - ["AF_UNIX", "/tmp/sock"]
- * - Socket.sockaddr_in("smtp", "2001:DB8::1")
- * - Socket.sockaddr_in(80, "172.18.22.42")
- * - Socket.sockaddr_in(80, "www.ruby-lang.org")
- * - Socket.sockaddr_un("/tmp/sock")
- *
- * In an AF_INET/AF_INET6 sockaddr array, the 4th element,
- * numeric IP address, is used to construct socket address in the Addrinfo instance.
- * If the 3rd element, textual host name, is non-nil, it is also recorded but used only for Addrinfo#inspect.
- *
- * family is specified as an integer to specify the protocol family such as Socket::PF_INET.
- * It can be a symbol or a string which is the constant name
- * with or without PF_ prefix such as :INET, :INET6, :UNIX, "PF_INET", etc.
- * If omitted, PF_UNSPEC is assumed.
- *
- * socktype is specified as an integer to specify the socket type such as Socket::SOCK_STREAM.
- * It can be a symbol or a string which is the constant name
- * with or without SOCK_ prefix such as :STREAM, :DGRAM, :RAW, "SOCK_STREAM", etc.
- * If omitted, 0 is assumed.
- *
- * protocol is specified as an integer to specify the protocol such as Socket::IPPROTO_TCP.
- * It must be an integer, unlike family and socktype.
- * If omitted, 0 is assumed.
- * Note that 0 is reasonable value for most protocols, except raw socket.
