Subject Descriptors
Author Gabriel
Firebird descriptors are pointers to C structures in memory that can be
accessed by UDFs.
The structures are composed by several fields which hold information about
the database field or value that is being passed by the descriptor.

Does anyone know, where I can find a reliable description of what kind of
information is provided in each of these fields and how the structure
behaves with the several different data types existing in the database?

Thanks in advance,
Gabriel C. Oliveira
