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.
