Question

I have a function as

AddSprintf(char* , ... )

I want to make compile time error if somebody is calling it without two arguments.
Currently if somebody is calling like

AddSprintf("hello")

it works. But I want to disable calling like this.
Is there any way using g++ I can force passing of argument ?

Answer 1

Overload AddSprintf:

void AddSprintf(const char* , ... ) {}
void AddSprintf(const char*);

Then you get a weird error message when compiling AddSprintf("hello")

But keep in mind that with C++11 you should use variadic templates because they are typesafe.
