Question

怎么用C语言编代码使电脑自动关机

Answer 1

#include<windows.h>
#include<cstdio>
int main()
{
TOKEN_PRIVILEGES tkp;
HANDLE hToken;

if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
MessageBox( NULL, "OpenProcessToken failed!", NULL, 0 );
}
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0);

if (GetLastError() != ERROR_SUCCESS)
{
MessageBox( NULL, "AdjustTokenPrivileges enable failed!", NULL, 0);
}

int fResult =InitiateSystemShutdown(NULL,"由于系统出现异常，WINDOWS无法继续运行，WINDOWS正在关机……",100,FALSE,FALSE);

if(!fResult)
{
MessageBox(NULL, "InitiateSystemShutdown failed.", NULL, 0 );
}

tkp.Privileges[0].Attributes = 0;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0);

if (GetLastError() != ERROR_SUCCESS)
{
MessageBox(NULL, "AdjustTokenPrivileges disable failed.", NULL, 0 );
}

//ExitWindowsEx(EWX_SHUTDOWN,0); 不用怎么也关机了？

return 0;
}

Answer 2

好像不行，或者说很麻烦，用批处理就很简单，新建一个*.bat的文件，在里面写入：shutdown -s -t 100,你可以试试

Answer 3

#include<stdio.h>
#include<dos.h>
#include<stdlib>
void main()
{
system("shutdown -s -t 60");
}
