 P: n/a * Alex Vinokur: Foo* p = new (nothrow) Foo; Should we use operator delete (p, nothrow) ? No. Or can we use delete p; ? Yes. -- A: Because it messes up the order in which people normally read text. Q: Why is it such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail? Nov 23 '06 #2

No. Can we use operator delete (p, nothrow) ? not like that, you must call it in a normal function call way if Foo has a delete operator like this void operator delete(void *, std::nothrow_t) Foo * p = new (std::nothrow) Foo; p->operator delete(p, std::nothrow); Nov 23 '06 #4
