[in] REFIID riid,
[out, iid_is(riid)] IUnknown** 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. |
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.
