missing includes?

missing includes?

[Andreas Fink]

On Debian9 Stretch

the 
	         struct sctp_sndinfo  send_info;

seems not to be defined in

	netinet/sctp.h

it seems however be defined in
 
	linux/sctp.h

but including both headers results in tons of redefinitions.

Also the definition of sctp_sendv is not found anywhere.


Whats the proper approach to use sctp_sndinfo for sctp_sendv()  in this case?

Normally, you should use netinet/sctp.h, which is from lksctp-tools and
copying from linux/sctp.h to make the header file for the released kernel
consistent with the uapi in lksctp-tools.

But if you update the kernel manually, the lksctp-tools should also be
updated. if Debian doesn't provide the newer version lksctp-tools, you
can go to upstream and build one:
https://github.com/sctp/lksctp-tools.git

BTW, sctp_sendv/recvv are supported since kernel 4.16, before
using it, make sure your kernel version is above 4.16.

Ok debian comes with Kernel 4.9. That explains things.
So I have to do use the old calls under Linux.

Amending, "... use the old calls under old Linux." :-)
