ShutDwnStart

The system software calls the ShutDwnStart procedure to restart a Macintosh computer.

PROCEDURE ShutDwnStart;

DESCRIPTION

The ShutDwnStart procedure initiates the final stage of restarting the system. It performs system housekeeping, executes any custom shutdown procedures installed with ShutDwnInstall, and restarts the computer. The system housekeeping functions consist of a five-step process, described in full in "The Shutdown Process" on page 8-4.

You should always call ShutDwnStart indirectly, through the Finder, to give any other applications running at the time a chance to exit gracefully. "Sending a Shutdown or Restart Event" on page 8-7 describes the correct way to restart a Macintosh computer.
