     specified message.

     The m argument is the opaque handle for the message involved in this
     operation.

RETURN VALUE
     Upon successful completion, the tt_message_class() function returns a
     value that indicates whether the sender wants an action to take place
     after the message is received.  The tt_message_class() function returns
     one of the following Tt_status values:

        TT_NOTICE
                A notice of an event.  The sender does not want feedback on
                this message.

                A request for some action to be taken.  The sender must be
                notified of progress, success or failure, and must receive any
                return values.

     The application can use tt_int_error(3) to extract one of the following
     Tt_status values from the Tt_class integer:
