# This method converts nodename (hostname) and service (port) to addrinfo. Since

# 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_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
