[Dev-C++] about exceptions

[Zodiaq <zo...@ac...>]

Hello all Dev-cpp-users,

  I have one important question - this small example will show what my
mail is all about... let's say I have one major function (FunQ) which
calls many smaller functions(fun1 - fun20), and all of these functions
uses the same small function (smallFun) which conditionaly may throw
exceptions... only FunQ catches these exceptions... is there some a
way to know which way this exception came apart from rethrowing it
from funX (where X is number 1-20)... adding in many points in every
fun1-fun20 try...catch is what I want to avoid... maybe there is
something similar like __LINE__ or __FILE__ but about call stack??

-- 
regards Zodiaq

As I see it, if you have a bottom level function throwing an exception, and
a top level function catching it, but to identify the mid-level function it
travelled through.. you would need to have to rethrow it in the midlevel
function with a minor tweak to identify itself.  I don't think there's any
way around that.

Hello Zodiaq,

You could have funX pass a code to smallFun which indicates 
what function called it (eg fun11 would pass 11 to FunQ), and
when smallFun throws an exception it can include this
code in the exception object, so that when FunQ catches it
it knows which function called smallFun.

[Per W. <pw...@ia...>]

Or do:
void fun() {
  int state = 0;

  try {
    fun1();
    state++;
    fun2();
    state++;
    fun3();
    state++
    ...
  } catch (x) {
    switch (sate) {
      case 0: cout << "fun1() is bad"; break;
      case 1: cout << "fun2() is bad"; break;
      ...
    }
  }
