关掉计算机ExitWindowsEx

[cai_c_cai]

ExitWindows或BOOL ExitWindowsEx(
UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);

[Flysnow]

BOOL ExitWindowsEx(
UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);

Parameters
uFlags
[in] Specifies the type of shutdown. This parameter must include one of the following values. Value Meaning
EWX_LOGOFF Shuts down all processes running in the security context of the process that called the ExitWindowsEx function. Then it logs the user off.
EWX_POWEROFF Shuts down the system and turns off the power. The system must support the power-off feature.
Windows NT/2000 or later: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.

EWX_REBOOT Shuts down the system and then restarts the system.
Windows NT/2000 or later: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.

EWX_SHUTDOWN Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped. If the system supports the power-off feature, the power is also turned off.
Windows NT/2000 or later: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.



This parameter can optionally include the following values. Value Meaning
EWX_FORCE Forces processes to terminate. When this flag is set, the system does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency.
EWX_FORCEIFHUNG Windows 2000 or later: Forces processes to terminate if they do not respond to the WM_QUERYENDSESSION or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.

BOOL InitiateSystemShutdownEx(
LPTSTR lpMachineName, // computer name
LPTSTR lpMessage, // message to display
DWORD dwTimeout, // length of time to display
BOOL bForceAppsClosed, // force closed option
BOOL bRebootAfterShutdown, // reboot option
DWORD dwReason // shutdown reason
);


Parameters

lpMachineName
[in] Pointer to the null-terminated string that specifies the network name of the computer to shut down. If lpMachineName is NULL or an empty string, the function shuts down the local computer.

lpMessage
[in] Pointer to a null-terminated string that specifies a message to display in the shutdown dialog box. This parameter can be NULL if no message is required.

dwTimeout
[in] Specifies the time (in seconds) that the shutdown dialog box should be displayed. While this dialog box is displayed, shutdown can be stopped by the AbortSystemShutdown function.
If dwTimeout is not zero, InitiateSystemShutdownEx displays a dialog box on the specified computer. The dialog box displays the name of the user who called the function, displays the message specified by the lpMessage parameter, and prompts the user to log off. The dialog box beeps when it is created and remains on top of other windows in the system. The dialog box can be moved but not closed. A timer counts down the remaining time before a forced shutdown.

If dwTimeout is zero, the computer shuts down without displaying the dialog box, and the shutdown cannot be stopped by AbortSystemShutdown.

bForceAppsClosed
[in] Specifies whether applications with unsaved changes are to be forcibly closed. If this parameter is TRUE, such applications are closed. If this parameter is FALSE, a dialog box is displayed prompting the user to close the applications.

bRebootAfterShutdown
[in] Specifies whether the computer is to restart immediately after shutting down. If this parameter is TRUE, the computer is to restart. If this parameter is FALSE, the system flushes all caches to disk, clears the screen, and displays a message indicating that it is safe to power down.

dwReason
[in] Specifies the reason for initiating the shutdown. This reason is recorded in the event log with event number 6006.
