HRESULT GetMaxThreads ( [out] DWORD *pdwMaxIoCompletionThreads );
[out] A pointer to the maximum number of threads in the thread pool that the host can allot to service I/O requests.
|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
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
GetMaxThreads. In this case, the host should return E_NOTIMPL from this method.
