#include <db_cxx.h> int DbEnv::get_cache_max(u_int32_t *gbytesp, u_int32_t *bytesp);
         The DbEnv::get_cache_max() method returns the maximum size of the
         cache as set using the 
         DbEnv::set_cache_max()
         method.

         The DbEnv::get_cache_max() 
            
            
                method either returns a non-zero error value or throws an
