a function-definition is not allowed here before '{' token

[Fransje]

Hi all,
I have this code:

#include <iostream>

#define func( returnType, name, params, body ) { \
    returnType name params { \
        body; \
    } \
}    

int main( int argc, char* argv[] ) {
    func( int, Add, ( int a, int b ), {
        return a + b;
    } );

    std::cout << Add( 5, 10 ) << std::endl;

    return 0;
}

But it gives the error in the title:
Line 13: error: a function-definition is not allowed here before '{' token
What is wrong?
Thanks!

You can't put the function definition inside another function ( main() is a function).

1. you can't define functions inside another function. you can call them, but not define them there.

2.

func( int, Add, ( int a, int b ), {
        return a + b;
    } );

    std::cout << Add( 5, 10 ) << std::endl;

you don't define the function "Add" like this

what you want is:

int Add(int a, int b)
{
   return a + b;
}

Ah, of course, I hadn't thought of that. Thanks!

@darkmaster: yeah, I know, but I am fascinated by define's and so I'm experimenting with them :)
