Detailed Description

ptr_fun() is used to convert a pointer to a function to a functor.

If the function pointer is to an overloaded type, you must specify the types using template arguments starting with the first argument. It is not necessary to supply the return type.

Example:
   void foo(int) {}
   sigc::slot<void, int> sl = sigc::ptr_fun(&foo);
Use ptr_fun#() if there is an abiguity as to the number of arguments.

Example:
   void foo(int) {}  // choose this one
   void foo(float) {}
   void foo(int, int) {}
   sigc::slot<void, long> sl = sigc::ptr_fun1<int>(&foo);
ptr_fun() can also be used to convert a pointer to a static member function to a functor, like so:

Example:
   struct foo
   {
     static void bar(int) {}
   };
   sigc::slot<void, int> sl = sigc::ptr_fun(&foo::bar);
