HRESULT EnterRuntime ();

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.

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.

NoteNote

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.
