Anthony - not sure what you are referring to here, because
the common use is to use the global errno made available
in libc. Is that not a proper errno?
Some libraries implement their own psuedo-errno to store library
specific errors. To the best of my knowledge, with the exception of
system libraries (libc) errno is not used and not really supposed to be
used.
I could be wrong, but I can't think of any libraries that use it.
thanks,
