Is there any way to test whether an application is running in Xcode or

I'm currently testing #ifdef DEBUG and simply assuming that Xcode is
the only compiler/debugger available on the Mac. But I understand that
isn't true.
#ifdef DEBUG is a compile time switch. You can run apps compiled with
DEBUG defined outside the debugger, too.
If you really need to know if you are running with a debugger attached,
the following might work (I did not test it!):
- fork into a new process, IPC to parent in place.
- regularly try:
int err = ptrace(PT_ATTACH, <pid>, (caddr_t)0, 0);
if (!err) ptrace(PT_CONTINUE, <pid>, (caddr_t)1, 0)
if (err == EBUSY) {
// Use IPC to inform parent: A debugger is attached.
}
I don't think there is a way to get the name of the process that is
attached as debugger.
