Subject: [Boost-users] [bind] how to get the type after bind

 //my question is how to write the type ??? below to make it run .

#include <boost/bind.hpp>
#include <iostream>
using boost::bind;
void print()
{
    std::cout <<" print" << std::endl;   
}

template <class T>
void func(T t)
{
    std::cout <<"func1(T t) : " ;
    t();       
}
int main()
{
    func(bind(&print));  //ok
          
    bind ( &func<???>, bind(&print) ) ; //don't know how to write it
}
 
[Nat] This doesn't directly answer your question; the type produced by bind() is obscure. But would the following suit your need? 
 
    bind ( &func< boost::function<void ()> >, bind(&print) ) ;
