◆ Set()
Send a DRAMA set message to the task.
This is the method for sending an SET message to the task referred to by this object - to set a parameter value. We must already have path to the task.
If this function returns DcppReschedule, then messages are expected and should be dispatched using DcppDispatch() when they arrive. This will ensure that future processing occurs correctly and the the appropriate handler is invoked when the operation completes.
- Returns
- DcppReschedule if a message was started. Otherwise DcppFinished and status will be set bad.
- Parameters
-
name | The name of the parameter to set. |
status | Inherited Status |
arg | The argument to the message, containing the value for the parameter. Defaults to SdsNull, a null argument. |
SuccessHandler | DcppDispatch() will invoke this if the operation completes successfully.
This function should return DcppReschedule if it sends another message.
Otherwise it should return DcppFinished.
The value returned will be returned by DcppDispatch(). If not specified, DcppDispatch() just returns DcppFinished. |
ErrorHandler | DcppDispatch() will invoke this if the operation fails after a message has been sent. This function should return DcppReschedule if it sends another message.
Otherwise it should return DcppFinished.
The value returned will be returned by DcppDispatch(). If not specified, DcppDispatch() just returns DcppFinished. |
ClientData | Passed directly to the handler functions. |
ErsHandler | DcppDispatch() will invoke this if a Ers message is received. If not specified, DcppDispatch just returns DcppReschedule, which is what your handler would normally return, since more messages are expected. This would normally only happen if the message was sent in UFACE context DitsInterested() was used to indicate an interest in ERS messages. |
