Plug-in Applications

You can create plug-in applications that contain script commands
that you create in order to extend the functionality of the built-in
script commands. A plug-in application is a standard .PRC
application that is installed on your HandEra computer just like any
other application. After you install the plug-in application on the
HandEra computer, the new script commands can be used in a login
script.
Plug-in applications have the following characteristics:
♦ Written in C language.
♦ Compiled into a device executable.
♦ Called properly from a login script.
♦ Able to return control to a login script after it terminates.
♦ Created using a development environment that supports the
Palm OS software, such as Metrowerks CodeWarrior.
