Thanks The idiom is something like this: void detect_exception() { try { throw; } catch (std::exception const& se) { // std::exception thrown } catch (myexception const& me) { // myexception thrown } catch (...) { // something else thrown } } /Peter Back to top Sylvester Hesp Guest Posted: Wed May 16, 2007 9:11 am    Post subject: Re: chained exception "josh" <xdevel1999 (AT) gmail (DOT) com> wrote in message news:1179302043.101088.112800 (AT) y80g2000hsf (DOT) googlegroups.com... Quote: Hi, is there a standard way to "read" an exception rethrowed by a catch and catch in an another extern try/catch? Thanks Sure there is, just use nested try/catch statements #include <iostream> int main() { try { try { std::cout << "throwing..." << std::endl; throw 42; } catch(int i) { std::cout << "Inner catch: " << i << " - rethrowing..." << std::endl; throw; } } catch(int i) { std::cout << "Outer catch: " << i << std::endl; } } Of course, the inner and outer catches don't have to be in the same function, and the outer catch can rethrow again if deemed necessary. - Sylvester Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
