Hi
I assume AppHandleEvent is in starter, and you include MainForm.h in
starter. If so then in MainForm.h you need to have the function
prototype/definition for MainFormHandleEvent in the .h file ie.
Boolean MainFormHandleEvent(EventPtr eventP);
This is because otherwise the linker does not know what the function
looks like when called from starter, and cannot link.
Ensure that you dont put "static" in front of it.
This a a C problem and not Palm problem. If you find yourself a book
that deals with multiple modules (c files) then it will explain all about
"static", "extern" etc and how data can be accessed between multiple files.
Its very easy once you have worked it out.
