You can study the IB6.0 Beta docs ApiGuide.pdf document to see what those connection structures are.

You don't need to know it. Firebird has an API that is surfaced in the client library. The API translation for Perl has already been done (to a great degree).

If you speak Perlspeak, you would probably work out quite a bit from studying the DBD::Interbase code that Ed Pratomo has developed from the past works of Bill Karwin, who originally developed a connectivity layer for Perl 5 and Interbase. 5.x I don't think Bill actively maintains IBPerl these days but the stuff that Ed has produced is here:

You can find all of the C defines, macros, et al., in ibase.h, in Firebird's /include/ directory.
