The InitiateSystemShutdown function initiates a shutdown and optional restart of the specified computer.
BOOL InitiateSystemShutdown(
LPTSTR lpMachineName, // pointer to name of computer to shut down
LPTSTR lpMessage, // pointer to message to display in
// dialog box
DWORD dwTimeout, // time to display dialog box
BOOL bForceAppsClosed, // force applications closed flag
BOOL bRebootAfterShutdown // reboot flag
);
If dwTimeout is not zero, InitiateSystemShutdown 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 the user logs off, the system shuts down immediately. Otherwise, the computer is shut down when the timer expires.
If dwTimeout is zero, the computer shuts down without displaying the dialog box, and the shutdown cannot be stopped by AbortSystemShutdown.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
To shut down the local computer, the calling process must have the SE_SHUTDOWN_NAME privilege. To shut down a remote computer, the calling process must have the SE_REMOTE_SHUTDOWN_NAME privilege on the remote computer. By default, users can enable the SE_SHUTDOWN_NAME privilege on the computer they are logged onto, and administrators can enable the SE_REMOTE_SHUTDOWN_NAME privilege on remote computers.
Common reasons for failure include an invalid or inaccessible computer name or insufficient privilege.
