Hi,
Excerpt from http://man7.org/linux/man-pages/man2/socket.2.html :
Some socket types may not be implemented by all protocol families;
for example, SOCK_SEQPACKET is not implemented for AF_INET.
This is not correct now, as Linux already had SCTP support.
Excerpt from http://tools.ietf.org/html/rfc6458#section-3.1.1 :
and one uses PF_INET or PF_INET6 as the domain, SOCK_SEQPACKET as the
type, and IPPROTO_SCTP as the protocol.
Here, SOCK_SEQPACKET indicates the creation of a one-to-many style
socket.
Regards,
Dongsheng
