IScheduledWorkItem::GetExitCode method (mstask.h)

  • Article

[[This API may be altered or unavailable in subsequent versions of the operating system or product. Please use the Task Scheduler 2.0 Interfaces instead.] ]

Retrieves the last exit code returned by the executable associated with the work item on its last run. The method also returns the exit code returned to Task Scheduler when it last attempted to run the work item.

Syntax

HRESULT GetExitCode(
  [out] DWORD *pdwExitCode
);

Parameters

[out] pdwExitCode

A pointer to a DWORD value that is set to the last exit code for the work item. This is the exit code that the work item returned when it last stopped running. If the work item has never been started, 0 is returned.

Return value

The GetExitCode method returns the error from the last attempt to start the work item. Possible values include the following.

Return code Description
S_OK
 The attempt to start the work item was successful.
SCHED_S_TASK_HAS_NOT_RUN
 No attempt has ever been made to start this work item.
E_INVALIDARG
 The arguments are not valid.
E_OUTOFMEMORY
 Not enough memory is available.

Remarks

This method can return the following two pieces of information:

  • The error or exit code that is returned by the executable that is being scheduled is returned in the pdwExitCode parameter.
  • The error code that the Task Scheduler received when it tried to start the job is returned in the GetExitCode method call itself.
To obtain an updated error code, always call ITaskScheduler::Activate first to obtain a new IScheduledWorkItem interface, which can then be used to obtain the updated error codes.

Examples

For an example of how to retrieve the creator of a task, see C/C++ Code Example: Retrieving Task Exit Code.
