如何在代码中模拟Delphi断点？ [英] How to simulate a Delphi breakpoint in code?

问题描述

我很确定我以前看过这个，但是我没有发现/记得如何做到这一点。我想要一行代码，当从Delphi调试器执行时，我希望调试器弹出，就像在该行上有一个断点。

如下所示：

  FooBar：= Foo（Bar）; 
 SimulateBreakPoint; //在Delphi IDE中导致断点发生在
 WriteLn（'Value：'+ FooBar）; 
  

希望这是有道理的。我知道我可以使用一个例外，但这样会是更多的开销，然后我想要。这是一些演示代码。

提前感谢！

解决方案

从代码触发调试器（据说我没有一个delphi的副本可以尝试）：

  asm int 3结束
  

看到这个页面：

I am pretty sure I have seen this before, but I haven't found out / remembered how to do it. I want to have a line of code that when executed from the Delphi debugger I want the debugger to pop-up like there was a break point on that line.

Something like:

FooBar := Foo(Bar);
SimulateBreakPoint; // Cause break point to occur in Delphi IDE if attached
WriteLn('Value: ' + FooBar);

Hopefully that makes sense. I know I could use an exception, but that would be a lot more overhead then I want. It is for some demonstration code.

Thanks in advance!

解决方案

To trigger the debugger from code (supposedly, I don't have a copy of delphi handy to try):

asm int 3 end;
