System and Environment Handles to MySQL Specific Resources
Two custom classes provide an interface to resources specific to a MySQL database. Note that using these classes reduces your database's portability.
*RWDBMySqlLibEnvironmentHandle is an environment handle returned by RWDBDatabase that provides methods allowing you to access or set various connect time and configuration parameters.
*RWDBMySqlLibSystemHandle contains the MYSQL structure used by the RWDBConnection, providing direct access to the MySQL C API.
