DESCRIPTION
     The tt_message_disposition_set() function sets the disposition attribute

     The m argument is the opaque handle for the message involved in this
     operation.  The r argument indicates whether an instance of the receiving

     the message is to be queued until the receiving process is started at a
     later time.  The following values are defined:

                returned to the sender with the Tt_status field containing
                TT_FAILED.

        TT_QUEUE
                Queue the message until a process of the proper ptype receives
                the message.

        TT_START
                Attempt to start a process of the proper ptype if none is
                running.

        TT_QUEUE+TT_START
                Queue the message and attempt to start a process of the proper
                ptype if none is running.

RETURN VALUE

     returns the status of the operation as one of the following Tt_status
     values:

                The ttsession(1) process is not running and the ToolTalk
                service cannot restart it.
