Description

WaitForAll calls DoWaitForAll, which waits for all the tasks in the array to be completed.

The WaitForAll method returns True if it succeeds, False otherwise.

Call the first overloaded WaitForAll method with the parameters described below:

Parameter Meaning
Tasks The array of tasks that should be completed before the calling tasks can continue.

Call the second overloaded WaitForAll method with the parameters described below:

Parameter Meaning
Tasks The array of tasks that should be completed before the calling tasks can continue.
Timeout The method waits a Timeout number of milliseconds for the array of tasks to be completed. If the Timeout occurs before the tasks are completed, the method will return False. This is a LongWord variable type.

Call the third overloaded WaitForAll method with the parameters described below:

Parameter Meaning
Tasks The array of tasks that should be completed before the calling tasks can continue.
Timeout The method waits a Timeout number of milliseconds for the array of tasks to be completed. If the Timeout occurs before the tasks are completed, the method will return False. This is a TTimeSpan variable type and it is converted to milliseconds before calling DoWaitForAll.
