There are a variety of reasons, some syntactic, but fundamentally, you can't do that in C directly (you'd have to mess about with pre-initialized data structures using the offsetof() macro), etc. You need a much higher-level language to do that sort of thing; or a much lower level (assembler) one. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
