Re: Why a try/catch in priority_queue::push/pop?!?
Hi Howard,
I think the try/catch is very old, coming from the HP/SGI STL, maybe
I missing historical facts which I'd like to know... Anyone helping?
<shakes head> Can't blame this one on HP/SGI, just checked, no-try/
catch there. :-)
I see... But I can find the strange beast already in libstdc++-v2, in
gcc2.95.3, a *lot* of time! (admittedly I never played myself with the
original HP/SGI STL, as distributed from the SGI web site, for example,
only some friends of mine did...)
I agree with your analysis of the code and the standard. I think the
user could reasonably expect priority_queue<int>::push to have the
strong exception guarantee, though I note that the standard doesn't
quite say that (that I can find).
Ok, thanks a lot for your reply. Then, for the time being, I think I
will simply remove the try/catch, then we'll see...
Paolo.
