This is a repost with the proper subject listed.
Sorry!
BTW: I have found the white paper on shared libraries
on the Palm WEB site.

This kind of hook may work for me. If I understand what your saying, I can
provide
an "interrupt handler" to do some work even though my application is not
running. By placing
it in a shared library, the system will have access to the routine at all
times. I'm not
familiar with shared libraries on the Palm, but I will start my
investigation. Any pointers on documentation about shared libraries and
the specific API you referred to would be appreciated.
Would I be able to send a "Launch Code" to my app from the interrupt?
