Return Value

HRESULT	Description
S_OK	CreateIoCompletionPort returned successfully.
HOST_E_CLRNOTAVAILABLE	The common language runtime (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_OUTOFMEMORY	Not enough memory was available to allocate the requested resource.

The CLR calls the CreateIoCompletionPort method to request that the host create a new I/O completion port. It binds I/O operations to this port through a call to the IHostIoCompletionManager::Bind Method method. The host reports status back to the CLR by calling ICLRIoCompletionManager::OnComplete Method.
