c++11 - C++: Creating a local copy of an Object -

-

i'm objective-c developer that's struggling c++ code.

below code have in c++:

ulconnection *conn; ...... //code builds connection conn->getlasterror()->getstring(value, 255);

i need create local copy (not reference) of getlasterror().

how local reference , check null?

here failed attempt:

ulerror error = *conn->getlasterror(); if (&error != null){}

as per understanding function conn->getlasterror() returns pointer of ulerror , need check return pointer null or not.

this work you.

const ulerror *error = conn->getlasterror(); if (error){}

since c++11 can follows instead comparing null

if( error != nullptr)
