Checks if you need to restart Windows

Version: 0.3.0

This utility returns a set of reboot event codes:

• Rename pending (1)
• Reboot pending (2)
• Reboot required (4)
• Notification is active (8)

Status codes of these events are defined in is_reboot_needed.h:

#define REBOOT_STATUS_CLEAN                0UL
#define REBOOT_STATUS_RENAME_PENDING       1UL
#define REBOOT_STATUS_REBOOT_PENDING       2UL
#define REBOOT_STATUS_REBOOT_REQUIRED      4UL
#define REBOOT_STATUS_NOTIFICATION_ACTIVE  8UL  /* a reboot notification is active (Windows 10) */

When system is not reboot needed this utility returns REBOOT_STATUS_CLEAN (zero value).

Set of these flags returns through the passed pointer to an int variable as the parameter of the is_reboot_needed function, that returns boolean value as a result if reboot is required.

Usage

is_reboot_needed [options]

    -a      Combination of '-s', '-d' and '-f' options.
    -s      Show status information. This is default option.
    -d      List driver updates, if present.
    -f      List update pending files.
    -n      Suppress logo.
    -q      Suppress all messages.
    -r      Automatic reboot if needed with no messages.
    -i      Start reboot if notification is active only (Windows 10).
            (used with '-r' option)

Warning: If you're use -r option and is reboot needed is TRUE, then system will be restarted immediately. Option -i allow reboot only if process MusNotifyIcon.exe is active (works for Windows 10)

Note: Since version 0.3.0 a special warning will be displayed when a reboot notification detected.
      The "REBOOT_STATUS_NOTIFICATION_ACTIVE" (8) flag has been added for the return code.
