c define multiline macro?

Question

#define DEBUG_BREAK(a)\\
    if ((a)) \\
{\\
    __asm int 3;\\
}

I have defined a macro as above, and try to use it

#include \"test_d         


        

Answer 1

That's weird, but getting {int 3} into brackets helps. And combining macro into singleliner doesn't. So it should be something about assembly, not the multilining.
