Yes, it seems you are right, I have read dlopen(3) in full on HP-UX,
this small detail is documented there. It seems I need to preload
the libraries:, and all the needed libs from
the target ODBC driver... Thanks for the info.

Bible has answers for everything. Proof:
"But let your communication be, Yea, yea; Nay, nay: for whatsoever is more
than these cometh of evil." (Matthew 5:37) - basics of digital technology.
"May your kingdom come" - superficial description of plate tectonics
