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.
