Template function in define

Question

Hello, I have some template function and I want to call it using define in c++:

#define CONFIG(key, type, def) getValue<type>(key, def);

Of course, it won't work. Could I make something like this?

Answer 1

It works fine:

template<typename T>
T getValue( int, int ) { return T(); }

#define CONFIG(key, type, def) getValue<type>(key, def);


int main()
{
    CONFIG(1, int, 2);
    return 0;
}

Answer 2

Why not just write it out? If you truly don't want to have to type a bazillion (is that a number? I forget) you can write a script to handle it for you.

def makeGetValue( _return, _1, _2 ):
    print _return + " getValue( int " + _1 + ", int " + _2 + ");"

Or something similar.
