Constructor Details
#new(sockaddr) ⇒ Object #new(sockaddr, family) ⇒ Object #new(sockaddr, family, socktype) ⇒ Object #new(sockaddr, family, socktype, protocol) ⇒ Object
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.

Class Method Details
.foreach(nodename, service, family = nil, socktype = nil, protocol = nil, flags = nil, &block) ⇒ Object
iterates over the list of Addrinfo objects obtained by Addrinfo.getaddrinfo.
Addrinfo.foreach(nil, 80) {|x| p x }
#=> #<Addrinfo: 127.0.0.1:80 TCP (:80)>
# #<Addrinfo: 127.0.0.1:80 UDP (:80)>

.getaddrinfo(nodename, service, family, socktype, protocol, flags) ⇒ Array .getaddrinfo(nodename, service, family, socktype, protocol) ⇒ Array .getaddrinfo(nodename, service, family, socktype) ⇒ Array .getaddrinfo(nodename, service, family) ⇒ Array .getaddrinfo(nodename, service) ⇒ Array
returns a list of addrinfo objects as an array.
This method converts nodename (hostname) and service (port) to addrinfo. Since the conversion is not unique, the result is a list of addrinfo objects.
nodename or service can be nil if no conversion intended.
family, socktype and protocol are hint for preferred protocol. If the result will be used for a socket with SOCK_STREAM, SOCK_STREAM should be specified as socktype. If so, Addrinfo.getaddrinfo returns addrinfo list appropriate for SOCK_STREAM. If they are omitted or nil is given, the result is not restricted.
Similarly, PF_INET6 as family restricts for IPv6.
flags should be bitwise OR of Socket::AI_??? constants such as follows. Note that the exact list of the constants depends on OS.
AI_PASSIVE Get address to use with bind()
AI_CANONNAME Fill in the canonical name
AI_NUMERICHOST Prevent host name resolution
AI_NUMERICSERV Prevent service name resolution
AI_V4MAPPED Accept IPv4-mapped IPv6 addresses
AI_ALL Allow all addresses
AI_ADDRCONFIG Accept only if any address is assigned
Note that socktype should be specified whenever application knows the usage of the address. Some platform causes an error when socktype is omitted and servname is specified as an integer because some port numbers, 512 for example, are ambiguous without socktype.
