| wij <wyniijj5@gmail.com>: Jul 16 02:27PM -0700 Snippet from https://www.geeksforgeeks.org/exception-handling-c/ #include <iostream> using namespace std; // Here we specify the exceptions that this function // throws. void fun(int *ptr, int x) throw (int *, int) // Dynamic Exception specification { if (ptr == NULL) throw ptr; if (x == 0) throw x; /* Some functionality */ } int main() { try { fun(NULL, 0); } catch(...) { cout << "Caught exception from fun()"; } return 0; } Note : The use of Dynamic Exception Specification has been deprecated since C++11. One of the reasons for it may be that it can randomly abort your program. This can happen when you throw an exception of another type which is not mentioned in the dynamic exception specification. Your program will abort itself because in that scenario, it calls (indirectly) terminate(), which by default calls abort(). ------------ "Caught exception from fun()" is not guaranteed (an illusion). Even throw specification would survive, the context loss problem is still unsolved. "Throw (std?)'exception' and let the caller knows how to deal with it deals with it" ... How convenient the "Advanced error handling mechanism" is! LIE, or like olcott, he did not know he kept lying all these years. |

In the early 80s, we had VAX-780s at UCSC, running 4.2BSD (not Open/Net/FreeBSD, just straight from Berkeley BSD). At the end of the semester one year, we got one of them up to a load average in the 70s. The thing slowed to a crawl, but... IT. DID. NOT. CRASH. Period. Rock solid. |
