I do not think that should be a function of the library !
The library user, i.e. your demon, may do so, anyway.

The library user, i.e. your demon, may do this too.

But why ?

I do not think I understand your problem here. For each SCTP instance
you registered, you can deregister it, to free your resources.
What do you think should _exactly_ be done in sctp_shutdownLibrary() ?

I am afraid not. What would it take to make them async-signal-safe ?
Best regards,
Andreas
