NAME

Pause request − 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 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. 

SEE ALSO
