Hi Eljay,

With same compiler, following program works well (compiles as well as
gives warning)
#include <stdio.h>

class myClass {
    public:
    int count() __attribute__((warn_unused_result));
};

int myClass::count() {
    return printf("hello world\n");
}

int main() {
    myClass obj;
    obj.count();
    return 0;
}

The only problem is, the program does not work if I define the method
inside the class. Any clue ??

Regards,
Mohan
