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()(). |
