IHostTaskManager::ReverseLeaveRuntime Method

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.

HRESULT ReverseLeaveRuntime ();

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.

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.
