C++ Language/Indirection/SmartPointers/SmartCompilerTemporary
Appearance
C++ creates a compiler-temporary for the new CRComplex(11,22)
portion of std::unique_ptr<CRComplex> piVar(new CRComplex(11,22));
.
To guard against memory leaks from exceptions occurring before that compiler-temporary is given to the smart pointer, use std::make_unique<CRComplex>(11,22)
in place of new CRComplex(11,22)
(a std::make_unique<>()
compiler-temporary is already a smart pointer as soon as it exists).
