CThreadPool::Initialize

  • Article

 

Call this method to initialize the thread pool.

Syntax

      HRESULT Initialize(
   void * pvWorkerParam = NULL,
   int nNumThreads = 0,
   DWORD dwStackSize = 0,
   HANDLE hCompletion = INVALID_HANDLE_VALUE 
) throw( );

Parameters

  • pvWorkerParam
    The worker parameter to be passed to the worker thread object's Initialize, Execute, and Terminate methods.

  • nNumThreads
    The requested number of threads in the pool.

    If nNumThreads is negative, its absolute value will be multiplied by the number of processors in the machine to get the total number of threads.

    If nNumThreads is zero, ATLS_DEFAULT_THREADSPERPROC will be multiplied by the number of processors in the machine to get the total number of threads.

  • dwStackSize
    The stack size for each thread in the pool.

  • hCompletion
    The handle of an object to associate with the completion port.

Return Value

Returns S_OK on success, or an error HRESULT on failure.
