IDebugThread2::GetThreadProperties

取得描述這個線程的屬性。

語法

int GetThreadProperties (
    enum_THREADPROPERTY_FIELDS dwFields,
    THREADPROPERTIES[]         ptp
);

參數

dwFields
[in]THREADPROPERTY_FIELDS 列舉中的旗標組合,決定要填入的欄位ptp

ptp
[in, out] 已填入線程屬性的 THREADPROPERTIES 結構。

傳回值

如果成功,則會傳回 S_OK;否則,會傳回錯誤碼。

備註

從這個方法傳回的資訊通常會顯示在 [ 線程 偵錯] 視窗中。

範例

下列範例示範如何針對實作 IDebugThread2 介面的簡單CProgram物件實作這個方法。

HRESULT CProgram::GetThreadProperties(THREADPROPERTY_FIELDS dwFields,
                                      THREADPROPERTIES *ptp)
{
    HRESULT hr = E_FAIL;

    // Check for valid argument.
    if (ptp)
    {
        // Create an array of buffers at ptp the size of the
        // THREADPROPERTIES structure and set all of the
        // buffers at ptp to 0.
        memset(ptp, 0, sizeof (THREADPROPERTIES));

        // Check if there is a valid THREADPROPERTY_FIELDS and the TPF_ID flag is set.
        if (dwFields & TPF_ID)
        {
            // Check for successful assignment of the current thread ID to
            // the dwThreadId of the passed THREADPROPERTIES.
            if (GetThreadId(&(ptp->dwThreadId)) == S_OK)
            {
                // Set the TPF_ID flag in the THREADPROPERTY_FIELDS enumerator
                // of the passed THREADPROPERTIES.
                ptp->dwFields |= TPF_ID;
            }
        }

        hr = S_OK;
    }
    else
        hr = E_INVALIDARG;

    return hr;
}
