IHostTaskManager::EnterRuntime Method

  • Article

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).

Syntax

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.
E_FAIL An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
E_OUTOFMEMORY Not enough memory was available to complete the requested allocation.

Remarks

EnterRuntime is called to notify the host that an unmanaged function, for which an earlier call to the LeaveRuntime method was made, has finished executing, and is returning execution control to the runtime.

Note

ReverseEnterRuntime 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.
