Registers a callback pointer for the specified event.
Syntax
HRESULT RegisterActionOnEvent (
[in] EClrEvent event,
[in] IActionOnCLREvent *pAction
);
Parameters
event
[in] One of the EClrEvent values, indicating the event for which to register the callback pointer described by pAction.
pAction
[in] A pointer to an IActionOnCLREvent object that is called when the registered event fires.
Return Value
| HRESULT | Description |
|---|---|
| S_OK | RegisterActionOnEvent 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. |
| 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. |
Remarks
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.
Note
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.
