TerminalClose

此函数命令终端完成操作。

bool  TerminalClose(
   int ret_code      // closing code of the client terminal
   );

参数

ret_code: [in] 返回代码，由客户端终端在操作完成时返回。

返回值

如果成功，该函数返回 true；否则返回 false。

注意

TerminalClose() 函数不会立即停止终端，它只是命令终端完成其操作。

调用 TerminalClose() 的专家顾问代码必须确保所有先前打开的文件以正常模式关闭。调用此函数后必须执行 return 运算符。

ret_code 参数允许指示启动终端操作时分析程序终止的原因所需的返回代码。
