Hi,

Is it possible to serialize function pointers? I'm trying to serialize this guy:

struct f { typedef void(*function_t)(); function_t the_ptr_; };

This was what I did to get my test to compile and run (same process, so it will work), which is totally not portable :) ar & boost::serialization::make_nvp("the_ptr_",boost::serialization::make_bin ary_object(&the_ptr_,sizeof(the_ptr_))); Any suggestions would be much appreciated. Thanks, Sohail
