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. The host reports status back to the CLR by calling ICLRIoCompletionManager::OnComplete.
