<ParallelTask variable>.Wait (Function) In french: <Variable TâcheParallèle>.Attend Waits for the end of execution of a parallel task.
// Triggers the execution of a task and waits for the task to be ended
t is ParallelTask = ParallelTaskExecute(Proc)
t.Wait() Syntax
<Result> = <Task>.Wait([<Maximum duration>])
<Result>: Boolean - True if the task is ended properly.
- False if the task is not ended properly. For example:
- the maximum task duration has been reached,
- the task was canceled.
<Task>: ParallelTask variable Name of the ParallelTask variable to be used. <Maximum duration>: Optional integer or optional Duration Maximum duration for running the task, expressed in hundredths of a second.- If this parameter is specified, <ParallelTask variable>.Wait locks the application until the task execution is ended or until the maximum duration is reached.
- If this parameter is not specified, <ParallelTask variable>.Wait locks the application until the task execution is ended.
This parameter can correspond to: - an integer corresponding to the number of hundredths of a second,
- a Duration variable,
- the indication of duration in clear ('1 s' or '10 ms' for example).
Remarks If <ParallelTask variable>.Wait is called from the main thread, the task to be waited for must not be executed in the main thread. Otherwise, a lock will occur. Indeed, the main thread cannot wait for the end of the task and run it at the same time. A WLanguage error signals the problem before the lock occurs.
