IHostThreadPoolManager::GetMaxThreads Method
Gets the maximum number of threads that the host maintains concurrently in the thread pool.
HRESULT GetMaxThreads (
[out] DWORD *pdwMaxWorkerThreads
);
Parameters
- pdwMaxWorkerThreads
[out] A pointer to the maximum number of threads that the host maintains in the thread pool.
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
The CLR calls GetMaxThreads to determine the total number of threads in the thread pool. The GetAvailableThreads method gets the number of threads that are not currently processing work items. All requests above the returned value of the pdwMaxWorkerThreads parameter remain queued until threads become available.
If the host does not provide an implementation of GetMaxThreads, it should return an HRESULT value of E_NOTIMPL.
