variadic template parameter pack expanding for function calls

Question

I am looking for something like that:

template< typename T>  
void func(T t)
{
}

template< typename... Parms> 
void anyFunc( Parms... p)
{
    f         


        

Answer 1

How about a small helper class:

template  struct Caller
{
  static void call(Func & f, A && a, Args && ...args)
  {
    f(std::forward(a));
    Caller::call(f, std::forward(args)...);
  }
};

template  struct Caller
{
  static void call(Func & f, A && a)
  {
    f(std::forward(a));
  }
};

template 
void Call(Func & f, Args && ...args)
{
  Caller::call(f, std::forward(args)...);
}

Then you can put the following in your client code:

void foo(A);
Call(foo, a1, a2, a3);
