        The DB_ENV->repmgr_site() method returns a 
        DB_SITE handle that defines a site's
        host/port network address. You use the DB_SITE
        handle to configure and manage replication sites.
    
This method allocates memory for the handle, returning a pointer to the structure in the memory to which sitep refers. To release the allocated memory and discard the handle, call the DB_SITE->close() method.
You must use the exact same host identification string and port number to refer to a given site throughout your application and on each of its sites.
         The DB_ENV->repmgr_site() method may be called at any time
         after the environment handle has been created.
    
         The DB_ENV->repmgr_site() 
            
                  method returns a non-zero error value on failure and 0 on success.
