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