    // Return Values:
    //  TRUE  - The string was sent to Process Monitor.
    //  FALSE - There was a problem sending the string to Process Monitor. To get

使用方法：

int _tmain(void)
{
    WCHAR szText[100];
    for (int i = 0; i < 20; i++)
    {
        _stprintf_s(szText,
                    _countof(szText),
                    L"ProcMon Debug Out Test # %d",
                    i);
        BOOL bRet = ProcMonDebugOutput(szText);
        if (TRUE == bRet)
        {
            _tprintf(L"Wrote %d\n", i);
        }
        else
        {
            _tprintf(L"error 0x%x\n", GetLastError());
        }
        ::Sleep(500);
    }
    return (0);
}

ProcMon配置：
