!     The arguments are:
!     \begin{description}
!     \item[clock]
!          The object instance to get the {\tt ESMF\_Alarm} from.
!     \item[alarmname]
!          The name of the desired {\tt ESMF\_Alarm}.
!     \item[alarm]
!          The desired alarm.
!     \item[{[rc]}]
!          Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
