IHostIoCompletionManager::CreateIoCompletionPort Method

Requests that the host create a new I/O completion port.

HRESULT CreateIoCompletionPort (
    [out] HANDLE *phPort
);

Parameters

  • phPort
    [out] A pointer to a handle to the newly created I/O completion port, or 0 (zero), if the port could not be created.

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.

Remarks

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.
