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

is called before milliseconds
elapses.
Return Value
HRESULT | Description |
---|---|
S_OK | Join returned successfully. |
HOST_E_CLRNOTAVAILABLE | The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully. |
HOST_E_TIMEOUT | The call timed out. |
HOST_E_NOT_OWNER | The caller does not own the lock. |
HOST_E_ABANDONED | An event was canceled while a blocked thread or fiber was waiting on it, or the current IHostTask instance is not associated with a task. |
