'__in_chrg' parameter in destructor

[vas04614]

Hi,

I saw couple of parameters in destructor's. Of course one was 'this' pointer, and other is '__in_chrg'. Can any one please let me know why this is used (heard because of virtual bases but not sure) and what does the value passed for it tell?

By,

Guys,

Any thoughts??

this is the current thing you are working on...

class something {
  int p;
  something(const int &set) : p(set);
  void donothing() { std::cout << this->p; }
};

something s(123);

s.donothing();

when donothing() is called with s the this is the variable s...

__in_chrg is probably defined where it is used... what are you looking at that has it?

If you could post whatever you found with that it would help.

OTOH, I believe this might have to do with whether or not the destructor must free the memory allocated to the object after it finishes.

__in_chrg would appear to be an internal parameter used by the compiler during exception handling.
