#include <db_cxx.h> int DbMpoolFile::get_priority(DB_CACHE_PRIORITY *priorityp);
         The DbMpoolFile::get_priority() method returns the cache priority for
         the file referenced by the DbMpoolFile
         handle.  The priority of a page biases the replacement algorithm to be
         more or less likely to discard a page when space is needed in the
         cache. This value is set using the 
         DbMpoolFile::set_priority()
         method.
    
         The DbMpoolFile::get_priority() method may be called at any time
         during the life of the application.
    
         The DbMpoolFile::get_priority() 
            
            
                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.
            
        
    
                          The DbMpoolFile::get_priority() method returns a reference to the
                          cache priority for the file referenced by the 
                          DbMpoolFile  handle in
                          priorityp.
