/*
 * This file implements a data structure that is built and maintained by the
 * preprocessor.
 *
 * All types that can be handled for host variable declarations has to
 * be handled eventually.
 */

/*
 * 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.
 *
 * Simle 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:
