  • Article

Registers a callback pointer for the specified event.

HRESULT RegisterActionOnEvent (
    [in] EClrEvent event,
    [in] IActionOnCLREvent *pAction
);

Parameters

  • event
    [in] One of the EClrEvent Enumeration values, indicating the event for which to register the callback pointer described by pAction.

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 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.
