#include <db.h> int DB->get_priority(DB *db, DB_CACHE_PRIORITY *priorityp);
         The DB->get_priority() method returns the cache priority for pages
         referenced by the DB 
         handle. This priority value is set using the 
         DB->set_priority()
         method.
    
         The DB->get_priority() method may be called only after the database has been opened.
    
         The DB->get_priority() 
            
                  method returns a non-zero error value on failure and 0 on success.
            
            
        
    
                          The DB->get_priority()
                          method returns a reference to the cache priority
                          in priorityp.
                          See DB->set_priority() 
                          for a list of possible priorities.
