descriptor. PARAMDSC is the descriptor itself, it describes what data
are stored in some area of memory. Just raw data in a format that we
define. The external procedure just reads raw data and returns raw data.

people understood it. Aleksey Karyakin corrects me that it should be
TLS and tells that it is bad thing to do.
Now I'm going to educate myself about TLSes and why they are evil in
C++, because in Java (and J2EE in particular) that is quite acceptable
way to handle things.
