NAME
     Pause - pause a tool, operation or data performance

SYNOPSIS
     Pause([in messageID operation]);

DESCRIPTION
     The Pause request pauses the specified  tool,  operation  or
     data performance.

     If the optional operation argument is included, the  handler
     should pause the operation that was invoked by the specified
     request.

     The operation argument is the request that should be paused.
     For  a  request to be eligible for pausing, the handler must
     have sent a Status notice back to the requester (thus  iden-
     tifying itself to the requester).

ERRORS
     The ToolTalk service may return the following error in  pro-
     cessing the Pause request:

        TT_DESKTOP_ENOMSG
              The operation argument does not refer to  any  mes-
              sage currently known by the handler.

APPLICATION USAGE
     The ttdt_session_join(3), and ttdt_message_accept(3),  func-
     tions  can  be  used  to register for, and help process, the
     Pause request.

EXAMPLES
     The Pause message can be sent as in the following example:

          Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
                      the_recipient_procid, TTDT_PAUSE,
                      my_callback);
          tt_message_send(msg);

WARNINGS
     Pause can also be sent as a multicast notice, as an edict to
     all  tools in the scope of the message.  The consequences of
     doing so can be severe and unexpected.

SEE ALSO

     ttdt_session_join(3); Resume request.
