Your code works fine, and is also completely independent of function_ptr, so might be useful as a utility in its own right. :) Anyway, regarding function_ptr, as modern C++ typically is generic, so that an entity only need to be "callable" (a function object or function pointer), and that function objects also supports binding of parameters, function_ptr probably have little use in modern C++. When it comes to APIs that use function pointers, it also needs to be a C++ API, as function_ptr can't be used as an "extern "C"" function. Also, the OP at the newsgroup prefers a macro to do this, after all, to avoid even stating the function signature. It was an interesting challenge, anyway. :) Regards, Terje _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
