I need to write something similar to fl_show_question(), in that it
will display a new form, allow interaction with it (and possibly, or
possibly not other forms, but thats incidental) and return a value to
the caller.
Its completely unclear to me how to do this. Once my routine calls
fl_show_form(), what can it do to allow interaction to proceed ?
If it calls fl_do_forms(), and was itself invoked from a callback by
fl_do_forms(), then the library gets used in a reentrant fashion, and
core dumps result at random.
If it calls fl_check_forms(), similar problems might arise, and
besides, the program turns into a CPU hog.
fl_show_question() appears to do something "magic" that invokes the
internals of fl_do_forms() but with reentrant issues. Can I get some
of that magic ?
--thanks,
