IHostThreadPoolManager Interface

Provides methods that enable the common language runtime (CLR) to configure the thread pool and to queue work items to the thread pool.

interface IHostThreadpoolManager : IUnknown {
    HRESULT GetAvailableThreads ( 
        [out] DWORD *pdwAvailableWorkerThreads
    );
    HRESULT GetMaxThreads ( 
        [out] DWORD *pdwMaxThreads
    );
    HRESULT GetMinThreads ( 
        [out] DWORD *MinThreads
    );
    HRESULT QueueUserWorkItem ( 
        [in] LPTHREAD_START_ROUTINE Function,
        [in] PVOID Context,
        [in] ULONG Flags
    );
    HRESULT SetMaxThreads (
        [in] DWORD MaxThreads
    );
    HRESULT SetMinThreads (
        [in] DWORD MinThreads
    );
};

Methods

Method	Description
IHostThreadPoolManager::GetAvailableThreads Method	Gets the number of threads in the thread pool that are not currently processing work items.
IHostThreadPoolManager::GetMaxThreads Method	Gets the maximum number of threads that the host maintains concurrently in the thread pool.
IHostThreadPoolManager::GetMinThreads Method	Gets the minimum number of idle threads that the host maintains in anticipation of requests.
IHostThreadPoolManager::QueueUserWorkItem Method	Queues a function for execution, and provides an object containing data to be used by the function.
IHostThreadPoolManager::SetMaxThreads Method	Sets the maximum number of threads that the host can maintain in the thread pool.
IHostThreadPoolManager::SetMinThreads Method	Sets the minimum number of idle threads that the host must maintain in anticipation of requests.

Remarks

The host is not required to configure the thread pool by using the values specified in calls to the SetMaxThreads and SetMinThreads methods. In this case, the host should return an HRESULT value of E_NOTIMPL from these methods.
