I'm sorry but none of the above makes much sense to me.

If you've already provided source code which illustrates whatever problems
you're seeing then, I apologize for missing it.  Please post it again.

Otherwise, statements like "SIGINT association was not successfully detached
when it is used in the contect of select ()" do not have any meaning to me.
