Pause (4)

Name

Pause - pause a tool, operation or data performance

Synopsis

Pause([in messageID operation]);

Description

Desktop Services Message Sets                                         Pause(4)



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 perfor-
       mance.

       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  identifying  itself  to  the
       requester).

ERRORS
       The ToolTalk service may return the following error in  processing  the
       Pause request:

          TT_DESKTOP_ENOMSG
                The operation argument does not refer to any message currently
                known by the handler.

APPLICATION USAGE
       The ttdt_session_join(3), and ttdt_message_accept(3), functions 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.
