IHostTask::Join Method

  • Artikkeli

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
[in] One of the WAIT_OPTION values. A value of WAIT_ALERTABLE instructs the host to wake the task if Alert 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.
E_FAIL An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
