Registers a callback pointer for the specified event.
HRESULT RegisterActionOnEvent ( [in] EClrEvent event, [in] IActionOnCLREvent *pAction );
[in] One of the EClrEvent values, indicating the event for which to register the callback pointer described by
[in] A pointer to an IActionOnCLREvent object that is called when the registered event fires.
|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.|
|E_FAIL||An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.|
The host can register callbacks for either or both of the two event types described by
EClrEvent. The host gets the
ICLROnEventManager interface by calling the ICLRControl::GetCLRManager method.
The events that
RegisterActionOnEvent registers can be fired more than once and from different threads to signal an unload or the disabling of the CLR.
