Requests that the host create a new task.

Syntax

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 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.

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 instance. The returned task must remain suspended until it is explicitly started by a call to IHostTask::Start.
