Db::get_cachesize(u_int32_t *gbytesp, u_int32_t *bytesp, int *ncachep);

The Db::get_cachesize() method returns the current size and composition of the cache. These values may be set using the Db::set_cachesize() method.

The Db::get_cachesize() method may be called at any time during the life of the application.

The Db::get_cachesize() method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
