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