系统关闭函数（例）

１、ExitWindowsEx

#include <tchar.h>
#include <windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
  HANDLE hToken;
  TOKEN_PRIVILEGES tkp;

  OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);

  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);
 
  ExitWindowsEx(EWX_SHUTDOWN, SHTDN_REASON_MAJOR_LEGACY_API);

  return 0;
}

２、InitiateSystemShutdown

#include <tchar.h>
#include <windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
  HANDLE hToken;
  TOKEN_PRIVILEGES tkp;
 
  OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);

  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);

  InitiateSystemShutdown(NULL, _T("Shutdown?"), 30, FALSE, FALSE);

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

  return 0;
}
