我这样写了一段C语言源程序，运行为什么无法关机!
我这样写了一段C语言源程序，运行为什么无法关机!

C/C++ code

#include<windows.h>void main(){    ExitWindowsEx(EWX_REBOOT, 0); }

[解决办法]
看看返回值
还有GetLastError看看结果

要先提升权限才行，参考下面的

C/C++ code

BOOL MySystemShutdown(){   HANDLE hToken;    TOKEN_PRIVILEGES tkp;     // Get a token for this process.     if (!OpenProcessToken(GetCurrentProcess(),         TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))       return( FALSE );     // Get the LUID for the shutdown privilege.     LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,         &tkp.Privileges[0].Luid);     tkp.PrivilegeCount = 1;  // one privilege to set       tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;     // Get the shutdown privilege for this process.     AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,         (PTOKEN_PRIVILEGES)NULL, 0);     if (GetLastError() != ERROR_SUCCESS)       return FALSE;     // Shut down the system and force all applications to close.     if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE,                SHTDN_REASON_MAJOR_OPERATINGSYSTEM |               SHTDN_REASON_MINOR_UPGRADE |               SHTDN_REASON_FLAG_PLANNED))       return FALSE;    return TRUE;}
