*************************************************************************
**
** This file demonstrates how to create a table-valued-function that
** returns the values in a C-language array.
** Examples:
**
**      SELECT * FROM array($ptr,5)
**
** The query above returns 5 integers contained in a C-language array
** at the address $ptr.  $ptr is a pointer to the array of integers that
** has been cast to an integer.
**
** There is an optional third parameter to determine the datatype of
** the C-language array.  Allowed values of the third parameter are
** 'int32', 'int64', 'double', 'char*'.  Example:
**
**      SELECT * FROM array($ptr,10,'char*');
**
** HOW IT WORKS
**
** The carray "function" is really a virtual table with the
** following schema:
**
**     CREATE TABLE carray(
