[Mono-dev] Implementing support of MPTCP Socket API in mono

[Antoine Cailliau]

Thanks Alex for the answer.

I lack documentation and/or example for my next problem.

I have a class similar to this:

> class MPTCPSubIds {
> ...
> MPTCPSubStatus[] SubStatus;
> ...
> }


and I need, in socket-io.c, to build the SubStatus array. I can create the
instance of MPTCPSubStatus without problem, but I do not find the
appropriate documentation/example to create the array and add the instances
in an array in my MPTCPSubIds object.

Any example or tips is warmly welcome :-)

Thanks in advance,

Antoine
