Token pasting

Hi,
How can I use token pasting preprocessor directive? I need to call the right function given the function names in the form of an array.

Code:

---

#define CallMyFun( p, n )  p->##n ();

string myFuncs[ 3 ] = { string( "Func1" ), string( "Func2" ), string( "Func3" ) };

class CMyClass
{
 public:
  bool Func1();
  bool Func2();
  bool Func3();
};

---

And then use it something like:

Code:

---

CMyClass theObject;
CallMyFun( &theObject, myFuncs[ 0 ].c_str() );

---

You can see the problem with the above code. How can I resolve the issue?
Thanks
SB
PS: Is there is another way of resolving the issue via function pointers. Note that the functions are not static members.

Yes, it's possible. Read about pointers to member functions.

A simple solution would be to create an std::map <std::string, bool(CMyClass::*)()>.

What about token pasting?

Think about what the compiler sees after pre-processing takes place.

When you type:

Code:

---

CMyClass theObject;
CallMyFun( &theObject, myFuncs[ 0 ].c_str() );

---

The compiler sees:

Code:

---

CMyClass theObject;
&theObject->myFuncs[ 0 ].c_str() ();

---

How do you plan on converting strings to actual symbol names?
