#include <db_cxx.h> int Db::get_re_len(u_int32_t *re_lenp);
        The Db::get_re_len() method returns the length of the records held
        in a Queue access method database. This value can be set using the
        Db::set_re_len()
        method.
    
         The Db::get_re_len() method may be
         called only after the database has been opened.
    
         The Db::get_re_len() 
            
            
                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 Db::get_re_len() method returns  the record
                          length in re_lenp. If the record length
                          has never been set using 
                          Db::set_re_len(), 
                          then 0 is returned.
