IHostTaskManager::ReverseLeaveRuntime Method

  • Article

Notifies the host that control is leaving the common language runtime (CLR) and entering an unmanaged function that was, in turn, called from managed code.

Syntax

HRESULT ReverseLeaveRuntime ();

Return Value

HRESULT Description
S_OK ReverseLeaveRuntime 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

The CLR calls ReverseLeaveRuntime to inform the host that the currently executing task is returning control to an unmanaged function that was, in turn, called from managed code through platform invoke. Each call to ReverseLeaveRuntime matches a corresponding call to ReverseEnterRuntime.
