/*
 * ShowDriverSettings
 * ShowDriverSettingsAfterFork
 *
 * When the user selects DevicesTab.<anydevice>.Properties.Settings, a
 * DRV_CONFIGURE message is sent to the selected user-mode driver, to cause
 * it to display its configuration dialog.  The sound drivers shipped with
 * NT (SNDBLST,MVAUDIO,SNDSYS) exhibit a bug in this condition: when the
 * configuration dialog is complete (regardless of whether OK or CANCEL was
 * selected), these drivers attempt to unload-and-reload their kernel-mode
 * component in order to begin using the new (or restore the original)
 * driver settings.  The unload request fails, because both the Audio tab
 * and SNDVOL.EXE have open mixer handles and pending IRPs within the kernel
 * driver (the latter are used to provide notifications of volume changes).
 * Worse, when the unload fails, it leaves the driver useless: its state
 * remains STOP_PENDING, and it cannot be resurrected without logging off
 * and back on.
 *
 * These routines have been provided as a temporary workaround for bug 15451,
 * which describes the problem mentioned above.  The theory behind this
 * solution is two-fold:
 *   1- close SNDVOL.EXE as soon as a driver's configuration dialog is
 *      to be displayed, and restart it directly thereafter.  This prevents
 *      it from maintaining any open handles to and/or pending IRPs within the
 *      kernel driver.
 *   2- if the Audio tab has ever been displayed, it will have open mixers
 *      which must be closed.  Because a bug/design flaw within these sound
 *      drivers prevents the mixers from being closed without killing this
 *      process (the sound drivers each cache open mixer handles), the
 *      routine ShowDriverSettings forks a new MMSYS.CPL process, which is
 *      then used to display the driver's settings dialog.
 *
 * The flow of this solution follows:
 *
 * 1- MMSYS.CPL starts on Audio tab, setting fHaveStartedAudioDialog to TRUE.
 * 2- User selects Devices tab.
 * 3- User selects a device driver.
 * 4- User selects Properties+Settings; control reaches ShowDriverSettings().
 * 5- ShowDriverSettings() determines if there is a need to fork a new process:
 *    this will be the case if the Audio tab has been displayed, and the
 *    device for which it is to display settings contains mixers.  If either
 *    of these conditions is false, ShowDriverSettings displays the driver's
 *    settings dialog directly (via ConfigureDriver()).
 * 6- ShowDriverSettings() uses WinExec() to fork a new process, using
 *    the routine ShowDriverSettingsAfterFork() as an entry point.  If the
 *    exec fails, ShowDriverSettings() displays the driver's settings dialog
 *    directly (via ConfigureDriver()).
 * PROCESS 1:                           PROCESS 2:
 * 7- Enters WaitForNewCPLWindow(),     1- ShowDriverSettingsAfterFork() will
 *    which will wait up to 5 seconds      receive on its command-line the
 *    for the new MMSYS.CPL process        name of the driver for which
 *    to open a driver Properties          settings have been requested.  It
 *    dialog which matches its own:        opens the primary dialog, using the
 *    if it finds such a dialog,           Devices tab as the initial tab--
 *    WaitForNewCPLWindow() will post      so that the Advanced tab is never
 *    IDCANCEL messages to both the        displayed, and because the Devices
 *    current driver Properties dialog,    tab is the active tab on the other
 *    and to this process's main           process.
 *    dialog, terminating this process. 2- During WM_INITDIALOG of the Devices
 *                                         dialog, this process searches for
 *                                       the previous process' MMSYS.CPL dialog.
 *                                     If successful, it moves this MMSYS.CPL
 *                                   dialog directly behind the previous dialog.
 *                              3- During ID_INIT of the Devices dialog, this
 *                               process searches the TreeView for the driver
 *                             which was named on the comand-line: if found,
 *                           it highlights the TreeItem and simulates a press
 *                         of the Properties button
 *                    4- During WM_INITDIALOG of the device's Properties dialog,
 *                     this process searches for the previous process' device's
 *                   properties dialog.  If successful, it moves this dialog
 *                 directly behind its counterpart.
 *            5- During ID_INIT of the device's Properties dialog, this process
 *             simulates a press of the Settings button
 *        6- When the Settings button is pressed, this process recognizes that
 *         it has been forked and skips the call to ShowDriverSettings(),
 *       instead simply displaying the driver's settings dialog (via
 *     ConfigureDriver()).
 *
 * Let it be known that this is a hack, and should be removed post-beta.

Routine Description:

    This routine acts as the class installer for Media devices.

Arguments:

    InstallFunction - Specifies the device installer function code indicating
        the action being performed.

    DeviceInfoSet - Supplies a handle to the device information set being
        acted upon by this install action.

    DeviceInfoData - Optionally, supplies the address of a device information
        element being acted upon by this install action.

Return Value:

    If this function successfully completed the requested action, the return
        value is NO_ERROR.

    If the default behavior is to be performed for the requested action, the
        return value is ERROR_DI_DO_DEFAULT.

    If an error occurred while attempting to perform the requested action, a
        Win32 error code is returned.
