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

Rewrite it as an inline function:

inline void DEBUG_BREAK(bool b)
{
    if (b) 
    {
        __asm int 3
    }
}

You may want to replace __asm int 3 with DebugBreak(), as that is the official MS function to do this.
