使用以下方法，能输出本进程的printf内容，但是脚本的print输出不了，与上一变更内容刚好互补就能实现所需需求；

// 创建stdout的管道;
if (!CreatePipe(&m_hStdOutRead, &m_hStdOutWrite, NULL, 0))
{
	printf("Error:创建stdout管道失败\n");
	return -1;
}

int wpfd = _open_osfhandle((intptr_t)m_hStdOutWrite, _O_TEXT);
FILE* pOutFile = _fdopen(wpfd, "w");
*stdout = *pOutFile;
setvbuf(stdout, NULL, _IONBF, 0);
