前阵子有朋友问我,怎么用C语言写一个小程序,控制电脑关机。这个我真的不懂,这几天闲着,就上网搜了搜,整理一下。
IDE: Code::Blocks 16.01
操作系统:Windows 7 x64
1 #include <windows.h> 2 3 int main() 4 { 5 system("shutdown -s -f -t 3600"); 6 Sleep(5000); 7 system("shutdown -a"); 8 9 return 0; 10 }
另外,需要添加链接库:libwsock32.a
右击工程,选“Build options...”
在“Project build options”对话框中,选“Linker settings” > “Add”,链接库“libwsock32.a”位于目录:CodeBlocksMinGWlib
之后,一路yes、ok、ok
关于“Shutdown”的参考:https://technet.microsoft.com/en-us/library/bb491003.aspx
-s : Shuts down the local computer.
-a : Aborts shutdown. Ignores other parameters, except -l and ComputerName. You can only use -a during the time-out period.
-f : Forces running applications to close.
-t xx : Sets the timer for system shutdown in xx seconds. The default is 20 seconds.
嗯,时间不早了,准备睡觉,试试下面的代码,看看效果。
1 #include <windows.h> 2 3 int main() 4 { 5 system("shutdown -s -f -t 60"); 6 7 return 0; 8 }
