ICLRRuntimeHost::SetHostControl Method

Sets the interface pointer that the common language runtime (CLR) can use to get the host's implementation of IHostControl Interface.

HRESULT SetHostControl(
    [in] IHostControl* pHostControl
);

pHostControl

[in] An interface pointer to the host's implementation of IHostControl Interface.

HRESULT

Description

S_OK

SetHostControl 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. If a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

E_CLR_ALREADY_STARTED

The CLR has already been initialized.

You must call SetHostControl before the CLR is initialized, that is, before you call ICLRRuntimeHost::Start Method or use any of the Metadata Interfaces. It is recommended that you call SetHostControl immediately after calling CorBindToCurrentRuntime Function or CorBindToRuntimeEx Function.
