c++ - return value of NEW -

-

it possible in cases new returns value, example null, or throw exception?

http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.6

take heart. in c++, if runtime system cannot allocate sizeof(fred) bytes of memory during p = new fred(), std::bad_alloc exception thrown. unlike malloc(), new never returns null!

[unless compiler "is ancient", in case page has solution you, too].

note if disable exceptions in compiler options, should check compiler docs can expect.
