class sigc::pointer_functor4< T_arg1, T_arg2, T_arg3, T_arg4, T_return >
pointer_functor4 wraps existing non-member functions with 4 argument(s). 
Use the convenience function ptr_fun() to create an instance of pointer_functor4.
The following template arguments are used:
template <class T_arg1 , class T_arg2 , class T_arg3 , class T_arg4 , class T_return > 
 
Constructs a pointer_functor4 object that wraps an existing function. 
- Parameters
- 
  
    | _A_func | Pointer to function that will be invoked from operator()(). |

Execute the wrapped function. 
- Parameters
- 
  
    | _A_a1 | Argument to be passed on to the function. |  | _A_a2 | Argument to be passed on to the function. |  | _A_a3 | Argument to be passed on to the function. |  | _A_a4 | Argument to be passed on to the function. |  
 
- Returns
- The return value of the function invocation.
