family should be an integer, a string or a symbol.
-
Socket::AF_INET, “AF_INET”, “INET”, :AF_INET, :INET -
Socket::AF_UNIX, “AF_UNIX”, “UNIX”, :AF_UNIX, :UNIX -
etc.
cmsg_level should be an integer, a string or a symbol.
-
Socket::SOL_SOCKET, “SOL_SOCKET”, “SOCKET”, :SOL_SOCKET and :SOCKET -
Socket::IPPROTO_IP, “IP” and :IP -
Socket::IPPROTO_IPV6, “IPV6” and :IPV6 -
Socket::IPPROTO_TCP, “TCP” and :TCP -
etc.
cmsg_type should be an integer, a string or a symbol. If a string/symbol is specified, it is interpreted depend on cmsg_level.
-
Socket::SCM_RIGHTS, “SCM_RIGHTS”, “RIGHTS”, :SCM_RIGHTS, :RIGHTS for SOL_SOCKET -
Socket::IP_RECVTTL, “RECVTTL” and :RECVTTL for IPPROTO_IP -
Socket::IPV6_PKTINFO, “PKTINFO” and :PKTINFO for IPPROTO_IPV6 -
etc.
cmsg_data should be a string.
