IHostTask::Join Method

  • Artikel

Blocks the calling task until the task represented by the current IHostTask Interface instance completes, the specified time interval elapses, or IHostTask::Alert Method is called.

HRESULT Join (
    [in] DWORD milliseconds,
    [in] DWORD option
);

Parameters

  • milliseconds
    [in] The time interval, in milliseconds, to wait for the task to terminate. If this interval elapses before the task terminates, the calling task unblocks.
  • option
    [in] One of the WAIT_OPTION Enumeration values. A value of WAIT_ALERTABLE instructs the host to wake the task if Alert is called before milliseconds elapses.
