IHostTaskManager::CreateTask Method

  • Article

Requests that the host create a new task.

HRESULT CreateTask (
    [in]  DWORD stacksize, 
    [in]  LPTHREAD_START_ROUTINE pStartAddress,
    [in]  PVOID pParameter,
    [out] IHostTask **ppTask
);

Parameters

  • stacksize
    [in] The requested size, in bytes, of the requested stack, or 0 (zero) for the default size.
  • pStartAddress
    [in] A pointer to the function the task is to execute.
  • pParameter
    [in] A pointer to the user data to be passed to the function, or null if the function takes no parameters.
  • ppTask
    [out] A pointer to the address of an IHostTask Interface instance created by the host, or null if the task cannot be created. The task remains in a suspended state until it is explicitly started by a call to IHostTask::Start Method.

Return Value

HRESULT Description

S_OK

CreateTask 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_OUTOFMEMORY

Not enough memory was available to create the requested task.

Remarks

The CLR calls CreateTask to request that the host create a new task. The host returns an interface pointer to an IHostTask Interface instance. The returned task must remain suspended until it is explicitly started by a call to IHostTask::Start Method.
