Could you clarify what does uncaught_exceptions_count() use look like? How is it different scope guard?
For instance, check first example at Boost.ScopeExit documentation (C++98 syntax): http://www.boost.org/doc/libs/1_53_0/libs/scope_exit/doc/html/index.html
void world::add_person(person const& a_person) { bool commit = false;
persons_.push_back(a_person); BOOST_SCOPE_EXIT(&commit, &persons_) { if(!commit) persons_.pop_back(); } BOOST_SCOPE_EXIT_END
// ...
commit = true; }
Using SCOPE_FAILURE it would became (C++98 syntax):
void world::add_person(person const& a_person) { persons_.push_back(a_person); SCOPE_FAILURE(&persons_) { persons_.pop_back(); } SCOPE_FAILURE_END
// ... }
I was asking specifically how uncaught_exception_count would be used. Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
