A version of DebugBreak that breaks the debugger without crashing the app

Is there a way to do something like DebugBreak() where when that function is hit the debugger breaks, but continue running when no debugger is attached?

I have a lua error handler that presents a user-friendly error message when something goes wrong, but if I'm debugging I want to stop execution as soon as I've detected something wrong.

I don't want to set a breakpoint in the debugger UI. I want a line of code that causes the debugger to break so I can share this breakpoint with co-workers.

Solution

  • You can use IsDebuggerPresent to check for an attached debugger, and then conditionally invoke DebugBreak:

    if (IsDebuggerPresent()) {
    DebugBreak();
}
