SCTP missing include file on OSX?

Question

I was messing around with sockets, and I wanted to test out using the SCTP protocol on my mac.

However, when I try to include the file netinet/sctp.h the compiler gives me a 'file not found' error.

So I did some digging, and sure enough, there is no include file for netinet/sctp.h on Mac OSX Lion. Why is that, when I can set up a socket with IPPROTO_SCTP, and it builds fine?

So, in summary, I have two questions:

Where are the headers for SCTP on Mac OSX?
Can I still set up a SCTP server without the proper headers? If so, how?

On Lion IPPROTO_SCTP is defined in netinet/in.h - that's why it worked just fine since you probably included netinet/in.h directly or indirectly. However, it is only present in Lion, not in any earlier OS X versions. (Note that netinet/sctp.h is not part of POSIX an I don't think it's portable)

Interesting. So does this mean I cannot use SCTP to set up a client-server socket on my Mac? – Richard J. Ross III Jan 14 '12 at 16:29

I fear not without a library - no sctp-specific functions are provided by OS X and creating a `IPPROTO_SCTP` sockets leads to `Protocol not supported` error. – Simon Urbanek Jan 15 '12 at 10:27

Just for completeness, you can run SCTP on OS X with a 3rd party extension: http://sctp.fh-muenster.de/ – Simon Urbanek Jan 15 '12 at 20:26

Looks like you could do

brew install libusrsctp

And you will see the installed header here, although it is probably a different implementation with a different name:

cat /usr/local/Cellar/libusrsctp/0.9.5.0/include/usrsctp.h
