)

public final function CancelTask (
    jobId : int, 
    taskId : int, 
    message : String
)

Parameters

jobId
The job identifier. The Cluster.AddJob method returns this value. If you have a job object that has already been added to the cluster, you can access the Job.Id property to get the identifier.

taskId
The task identifier. To get this value, access the Task.Id property.

message
A message that describes the reason why the task was canceled. The message is limited to 320 Unicode characters. This parameter can be NULL.

The message is stored with the task. To get the message, access the Task.ErrorMessage property.

Remarks

To cancel a task, the task's status must be: not submitted, queued, or running. If a task is running when it is canceled, the task is terminated and the status of the task changes to Cancelled (see TaskStatus). To determine a task's status, access the Task.Status property.

You can call the Cluster.RequeueTask method to queue the task again.
