Open the Windows SDK help file and navigate to "System Shutdown Functions". 
Or, search the help for ExitWindows or ExitWindowsEx.

Also, this question has been asked an uncountable number of times before. 
Head to http://groups.google.com and search for something like "cppbuilder 
restart windows".

> How can I restart windows XP from my Program?

This has been discussed many times before.

// For example, try this function, with argument mode = 1:
void SystemShutDown( int mode )
{
   HANDLE hToken;
   TOKEN_PRIVILEGES tkp;

   AnsiString error;

   // Get a token for this process.
   if ( !OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | 
TOKEN_QUERY, &hToken ) )
      error = "OpenProcessToken";

   // 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 );

   // Cannot test the return value of AdjustTokenPrivileges.
   if ( GetLastError() != ERROR_SUCCESS )
      error = "AdjustTokenPrivileges";

   switch( mode )
   {
      // 0 = Forcefully close apps, shutdown and leave system at shutoff 
point
      case 0:   if ( !ExitWindowsEx( EWX_SHUTDOWN | EWX_FORCE, 0 ) )
                   error = "ExitWindowsEx";
                break;

      // 1 = Forcefully close apps, shutdown and reboot
      case 1:   if ( !ExitWindowsEx( EWX_REBOOT | EWX_FORCE, 0 ) )
                   error = "ExitWindowsEx";
                break;

      // 2 = Forcefully close apps, and logoff
      case 2:   if ( !ExitWindowsEx( EWX_LOGOFF | EWX_FORCE, 0 ) )
                   error = "ExitWindowsEx";
                break;

      // 3 = Forcefully close apps, shutdown and poweroff
      case 3:   if ( !ExitWindowsEx( EWX_POWEROFF | EWX_FORCE, 0 ) )
                   error = "ExitWindowsEx";
                break;
   }
}

Alternatively, you can call shutdown command:

   system( "shutdown -r -f -t 03" )
or:
   system( "shutdown -s -t 00" )
... but look at arguments for meanings (restart, logoff, shutdown ,...).
