IHostTaskManager::EnterRuntime Method
Notifies the host that a call to an unmanaged method, such as a platform invoke method, is returning execution control to the common language runtime (CLR).
HRESULT EnterRuntime ();
Return Value
| HRESULT | Description |
|---|---|
S_OK |
EnterRuntime returned successfully. |
HOST_E_CLRNOTAVAILABLE |
The 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. |

Remarks
EnterRuntime is called to notify the host that an unmanaged function, for which an earlier call to the IHostTaskManager::LeaveRuntime Method method was made, has finished executing, and is returning execution control to the runtime.
Note
IHostTaskManager::ReverseEnterRuntime Method is called to notify the host that an unmanaged function, for which an earlier call to LeaveRuntime was made, is making a call into managed code.
