Cannot open SCTP Socket with socket type SOCK_DGRAM

Question

int sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_SCTP);

the returned error is 93 on CentOS 3.2.63 and 10043 on windows 8 which means Protocol not supported. But I can open the socket successfully with socket type SOCK_RAW,SOCK_STREAM. Can't open with SOCK_SEQPACKET in windows 8 but can open in CentOS.

SCTP must be used with either SOCK_SEQPACKET or SOCK_STREAM. See Sockets API Extensions for the Stream Control Transmission Protocol (SCTP), RFC 6458 for more details on how to use SCTP.

Not all OS support SCTP and even existing support might miss some features.

If I don't want to use thirdparty library then I have to implement SCTP on my own on windows platform? – Tahlil Jan 21 '15 at 06:25

Yes, there does not seem to be native support for it. – Steffen Ullrich Jan 21 '15 at 06:52
