Question:
How do I programmatically shutdown windows?
Answer:
As such:
bool WINAPI SystemRestart (DWORD mode)
{
BOOL ret;
OSVERSIONINFO vi;
vi.dwOSVersionInfoSize = sizeof(vi);
GetVersionEx (&vi);
if (vi.dwPlatformId == VER_PLATFORM_WIN32_NT) {
HANDLE hToken;
TOKEN_PRIVILEGES tp;
ret = FALSE;
if (OpenProcessToken (GetCurrentProcess (), // open access privilege list.
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) {
tp.PrivilegeCount = 1;
LookupPrivilegeValue (NULL, SE_SHUTDOWN_NAME, // Ask the "shutdown" LUID
&tp.Privileges[0].Luid);
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; // enable it
AdjustTokenPrivileges (hToken, FALSE, &tp, 0, NULL, 0);
ret = (GetLastError () == ERROR_SUCCESS);
}
}
else
ret = true;
return (ret ? ExitWindowsEx (mode, 0) : false);
}
