It can be done. I've wanted to add a "case study" to the documentation but never have gotten around to it.
Basically here is the procedure.
a) Use a function object rather than a function pointer. This should be easy to do. b) derive your function object from a common base class make your function a virtual member of this class c) make sure that the common base class has at least one virtual function. This makes it a polymorphic base class. d) include a variable which is a pointer to the common base class - that is a polymorphic pointer. e) Assign a new function object of the desired derived type to the polymorphic pointer. f) Save the polymorphic pointer as you would any other polymorphic pointer. g) Some other time and/or place, load the polymorphic pointer as you would any other polymorphic pointer. h) You can now call your original function through the pointer to it's base class
Arguably, with this technique you're not serializing a function pointer. :) Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
