IHostTaskManager::ReverseEnterRuntime Method

Notifies the host that a call is being made into the common language runtime (CLR) from unmanaged code.

HRESULT ReverseEnterRuntime ();

Return Value

HRESULT	Description
S_OK	ReverseEnterRuntime 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 is available to complete the requested resource allocation.

Remarks

If the call into the CLR is made from a sequence that originated in managed code, each call to ReverseEnterRuntime corresponds to a call to IHostTaskManager::ReverseLeaveRuntime Method.

Note

Calls can originate from unmanaged code without being nested. In this case, there is no call to IHostTaskManager::EnterRuntime Method, IHostTaskManager::LeaveRuntime Method, or ReverseLeaveRuntime, and the number of calls to ReverseEnterRuntime does not equal the number of calls to ReverseLeaveRuntime.
