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:
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)
