在应用程序中使用系统功能重启系统的最佳方法是什么？

问题描述

亲爱的开发人员，

问候!!!!

因为，我想重新启动基于WinCE 7的系统应用。我正在使用一个系统定义的函数  SetSystemPowerState。
以下是示例代码 -

As, i would like to reboot my WinCE 7 based system with an application. I am using one system defined function SetSystemPowerState.Below is the sample code -

DWORD result;
	result = SetSystemPowerState(NULL, POWER_STATE_BOOT,0);
	if(result){
		DEBUGMSG(TRUE,(TEXT("The system is going to boot\r\n")));
	}
	else{

		DEBUGMSG(TRUE,(TEXT("ERROR: While trying to reboot the system :%d\r\n"),GetLastError()));
	}

但是，当我运行我的应用程序时，我收到了以下调试消息 -

But, when I run my application I got the following debug messages -

但是，系统无法启动。根据上述观察得出的任何结论???

But, the system does not boot. Any conclusion with the above observations???

推荐答案

对于x86平台 - 请尝试使用SetSystemPowerState（NULL， POWER_STATE_RESET ，POWER_FORCE）。

for x86 platforms - try SetSystemPowerState (NULL, POWER_STATE_RESET, POWER_FORCE) instead.

默认重启例程位于@ WINCE700\platform\common\src\x86\common\ioctl\reboot.c，但自定义BSP可能将其移植到自身。

Default reboot routine is located @ WINCE700\platform\common\src\x86\common\ioctl\reboot.c, but custom BSP may port it to itself.

祝你好运。
