IHostControl::GetHostManager Method

Gets an interface pointer to the host's implementation of the interface with the specified IID.

HRESULT GetHostManager (
    [in] REFIID riid,
    [out, iid_is(riid)] void** ppObject
);

riid

[in] The IID of the interface that the common language runtime (CLR) is querying for.

ppObject

HRESULT

Description

S_OK

GetHostManager 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_INVALIDARG

The requested IID is not valid.

E_NOINTERFACE

The requested interface is not supported.

The CLR queries the host to determine whether it supports one or more of the following interfaces:

If the host supports the specified interface, it sets ppObject to its implementation of that interface. Otherwise, it sets ppObject to null.

The CLR does not call Release on host managers, even when you shut it down.
