Sorry if this is documented somewhere - I've searched and cannot find it. How can I embed a debug break in an OSX console .c app that I'm debugging with gdb? I see in the "debugging magic" technote something about setting the USERBREAK environment variable and using SysBreak() or Debugger(). I tried including MacTypes.h - but I still get a link error for SysBreak() or Debugger(). So - my question is simple - how can I add a debug break in my console app?

Thanks,

This macro should do what you want w/o the need for Carbon:

#ifdef __ppc__
#define trap() asm volatile("trap")
#elif __i386__
#define trap() asm volatile("int $3")
#else
#error unknown arch
#endif

HTH.
