Seems reasonable for me, but if the ULP uses a wrong pointer
you probabily modify some important part of your memory ...
What about having an array of the assoc data (or at least an
array of pointers to these data) and use an index. Than you
can do at least some array index bounds checking.
I think that is a good thing for an API.
Happy SCTPing
