/*
* This file implements a data structure that is built and maintained by the

*/
/*
* Here are all the types that we are to handle. Note that it is the type
* that is registered and that has nothing whatsoever to do with the storage
* class.
*
* Simple types
* integers: char, short, int, long (signed and unsigned)
* floats: float, double
*
* Complex types:
* VARCHAR, VARCHAR2 - Strings with length (maxlen is given in the declaration)
* Arrays of simple types and of VARCHAR, VARCHAR2 (size given in declaration)
* Records build of simple types, arrays and other structs.
*
* Complicating things:
* typedefs and struct names!
*
* Conclusion:
* This is a typically recursive definition. A structure of typed list elements
* would probably work fine:
