Hi, I'm sorry, this is a repost of a message I send to boost user, with a somewhat more restrictive subject. I didn't get any input there, and I hope that someone can help me here. I'm currently trying to wrap (or forward) a call to boost::signal<A_func_Signature>::connect(), to - amongst other things - insulate users from using boost::bind. So what I have is something like this: template< typename Signature, class Reciever > void connect( const signal_id& id, const Signature& sig, const Reciever* rcv ) { typedef ???? AdaptedSignature; get_signal< AdaptedSignature > ( id ) -> connect(boost::bind(sig, rcv, _1)); } now this code is supposed to be called like this: connect( some_signal_id, &SomeClass::some_member, someClass_instance ); where SomeClass::some_member has the same function signature as the signal which is associated with some_signal_id. e.g. boost::signal<void (bool)> signal; struct SomeClass { void some_member(bool b); }; So my question is how can I construct the "AdaptedSignature" type from the template deduced "Signature"? From what I gather from the documentation, boost function_types might hold the answer to my question, but I cannot figure out how. So is what I am trying to do possible, and is function_types the right tool? TIA Fabio
