//////////////////////////////////////////////////
Why RESTART?
//////////////////////////////////////////////////

It is sometimes necessary to restart Windows in order to have 
changes in the system (i.e., WIN.INI, SYSTEM.INI) files take effect.
RESTART allows you to do this without having to exit, and then
restart.

//////////////////////////////////////////////////
Program Usage and Syntax
//////////////////////////////////////////////////

Syntax:  RESTART [/R | E]
        Switches:  R - Restart Windows
                   E - Exit Windows

NOTE:  Invoking RESTART using the command line switches automatically 
turns confirmation on.

RESTART, as its name implies, is a small utility that allows 
the user to restart Windows, or exit it.  To use it, simply 
execute RESTART, select the desired action, and press Go!. 
You can quit the program by selecting Cancel, or Close in the
system menu. The dialog box contains a "Confirmation On" 
checkbox. Uncheck this box to avoid the confirmation dialog
box.

You can set RESTART to run automatically by creating an icon in
Program Manager.  Simply create a new program icon, and then
enter the command line switch that you desire.  For example to
have RESTART restart Windows without invoking the main dialog box,
simply enter:  C:\UTIL\RESTART /R.

//////////////////////////////////////////////////
Technical Details
//////////////////////////////////////////////////

RESTART is written in C and is compiled using Microsoft C/C++
7.0 and the Windows 3.1 SDK.  The code is written based upon
a similar design by Mike Sax, as originally written in Dr. 
Dobbs Journal (UNLOAD.EXE).  The original code is available for
anonymous FTP from SIMTEL20 as /pub/msdos/ddj/ddj0992.zip.  

When RESTART is invoked, it calls the function ParseCmdLine(),
which determines if any command line switches have been used.
If they have, the variable bCmdLineParam is set to TRUE, and,
depending upon the switch, the variable Action is set either to
EW_RESTARTWINDOWS or NULL (see below).  If an incorrect switch
is used, the program notifies the user and invokes the main
dialog box.

If no command line parameter has been used, the main dialog box
is created normally, and RESTART waits for user input.  The
program works by checking the status of the radio buttons
when Go! is pressed:

        int Action;
        BOOL bAnswer, bSuccess;
        
        Action = (IsDlgButtonChecked(hDlg, IDD_RESTART)) ?
                EW_RESTARTWINDOWS : (IsDlgButtonChecked (hDlg, 
                IDD_EXIT)) ? NULL : NOCHECK;
        if (Action == NOCHECK)
                {
                MessageBeep(0);
                break;
                }
        bAnswer = AreYouSure (hDlg, Action);
        if (!bAnswer) break;
        bSuccess = MakeItSo (Action);
        if (!bSuccess) {
                MessageBox (hDlg, "One or more  \
                applicatons refused to          \
                terminate!", szAppName, MB_OK);
                }
        break;
        
The MakeItSo() function simply passes the results of the
IsDlgButtonChecked() call to ExitWindows():

        ExitWindows (Action, 0);

ExitWindows() actually can accept 3 different options:
EW_RESTARTWINDOWS, EW_REBOOTSYSTEM, or NULL.  EW_REBOOTSYSTEM
will cause Windows to terminate and the system to restart.
