Read it at the original source: ## Questions this post answers ### When should I use std::move when returning a value from a C++ function? Generally you should not use std::move on a local variable being returned, because it can suppress return value optimization or named return value optimization (NRVO), forcing a move instead of eliminating the copy entirely. The compiler already applies RVO/NRVO automatically in most cases, making an explicit std::move unnecessary and sometimes counterproductive. _Developers sorting out move semantics pitfalls can find deeper C++ explainers curated on daily.dev._ ## Similar posts on daily.dev - [C\+\+ Insights Episode 74: Why move requires noexcept in C\+\+20](https://daily.dev/posts/c-insights-episode-74-why-move-requires-noexcept-in-c-20-uhelxmxyk) · Andreas Fertig · 0 upvotes · 0 comments - [std::move doesn't move anything: A deep dive into Value Categories](https://daily.dev/posts/std-move-doesn-t-move-anything-a-deep-dive-into-value-categories-hbbu5zmdc) · Hacker News · 1 upvotes · 0 comments --- Tags: [#c++](https://daily.dev/tags/c++), [#compiler-optimization](https://daily.dev/tags/compiler-optimization) [View this post on daily.dev](https://daily.dev/posts/c-insights-episode-77-rvo-nrvo-std-move-explained-jyxuxt35e)
