self primitivePerror.

Imagine that the C lib called from #primitiveWhatever was the one setting errno.

My question is... the following #primitivePerror is a DIFFERENT system call. Couldn't that happened that another error happened before the first system call and time I am executing the second one and so the "last error" (errno) is actually the wrong one I am thinking of?

Even worst, I may think that the scope of the ��"global variable errno" may existed at the scope of the invoked lib only? In this case I don't have above problem, but then....how can I get such number once the NB primitive finished (so that I can call, for example, ��strerror() ? ��

Thanks in advance,��
