IHostIoCompletionManager::SetMinThreads Method

  • Artikkeli

Sets the minimum number of threads that the host should allot to I/O completion.

Syntax

HRESULT SetMinThreads (  
    [in] DWORD dwMinIoCompletionThreads  
);

Parameters

dwMinIoCompletionThreads
[in] The minimum number of I/O completion threads that the host should create.

Return Value

HRESULT Description
S_OK SetMinThreads 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_NOTIMPL The host does not provide an implementation of SetMinThreads.

Remarks

A host might want exclusive control over the number of threads that can be allotted to process I/O requests, for reasons such as implementation, performance, or scalability. For this reason, the host is not required to implement SetMinThreads. In this case, the host should return E_NOTIMPL from this method.
