[family address-info-family] [type address-info-type] [host address-info-host] [port address-info-port]) </verbatim> Descriptor for an internet socket address. The family is either <tt>'ipv4</tt> or <tt>'ipv6</tt>. The type is either <tt>'tcp</tt>, <tt>'udp</tt> or <tt>'raw</tt>. The host is a numeric address encoded as a string. The port is a either a positive integer or <tt>#f</tt>. <h2>Address Info Lookup</h2> <verbatim> (address-infos HOST [#:port PORT] [#:family FAMILY] [#:type TYPE] [#:server? BOOLEAN] [#:numeric? BOOLEAN]) => (list ADDRESS-INFO ...) | #f </verbatim> Tries to lookup socket addresses for the given host and/or port. If the lookup is successful, the procedure returns a list of address information records. Otherwise it returns <tt>#f</tt>. For a successful lookup you must at least specify a hostname or a port. If no hostname is specified, the function defaults to server mode lookup and will return wildcard addresses. This behaviour can be changed using the <tt>#:server?</tt> flag. By default, the procedure will return address information records for all suitable supported protocol families and socket types. The <tt>#:family</tt> argument may be used to filter for <tt>'ipv4</tt> or <tt>'ipv6</tt> addresses. The <tt>#:type</tt> argument may be used to filter for <tt>'tcp</tt> / <tt>'stream</tt>, <tt>'udp</tt> / <tt>'datagram</tt> or <tt>'raw</tt> socket types. Unless the <tt>#:numeric?</tt> flag is set to a true value, the procedure will convert hostnames into numeric network addresses. |
