Window下，在TEMP路径下生成一个临时文件名

BOOL GetFullTempFileName(const TCHAR* strPrefix, std::wstring&strFullName)

{

    TCHAR strTempFolder[MAX_PATH];

    TCHAR strTempFileName[MAX_PATH];

    DWORD dwRetVal= GetTempPath(MAX_PATH,          //length of the buffer
                           strTempFolder); //buffer for path
    if (dwRetVal > MAX_PATH || (dwRetVal == 0))

    {returnFALSE;

    }//Generates a temporary file name.
    UINT uRetVal = GetTempFileName(strTempFolder, //directory for tmp files
                              strPrefix,           //temp file name prefix
                              0,                   //create unique name
                              strTempFileName);    //buffer for name
    if (uRetVal == 0)

    {returnFALSE;

    }//返回回去
    strFullName =strTempFileName;returnTRUE;
