Use a Callback Function

You can use a callback function (with the OnEvent function) to perform housekeeping tasks before the system shuts down. You would normally call OnEvent in the main startup function (defined with the [Code]Startup parameter). Each time a Shutdown() call is made, the callback function is run.

/* A user shutdown procedure. */

INT

FUNCTION

MyStartupFunction()

...

OnEvent(25, MyShutdown);

...

END

INT

FUNCTION

MyShutdown()

STRING sPath;

// Perform housekeeping tasks

...

sPath = ProjectCurrentGet();

If sPath = "ProjectA" Then

ProjectSet("ProjectB");

Else

ProjectSet("ProjectA");

END

Shutdown("Everybody", sPath, 2);

END
