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)] IUnknown** ppObject
);

Parameters

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

  • ppObject
    [out] A pointer to the host-implemented interface, or null if the host does not support this interface.

Return Value

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.

Remarks

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.

Requirements

Platforms: Windows 2000, Windows XP, Windows Server 2003 family
