Resource acquisition is initialization (RAII) is a programming idiom used in several object-oriented, statically-typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant, and is tied to object lifetime. Resource allocation (or acquisition) is done during object creation (specifically initialization), by the constructor, while resource deallocation (release) is done during object destruction (specifically finalization), by the WebMar 31, 2008 · Programming RAII Threads If boost::threads represent the C of multithreaded programming, then RAII and automatically managed threads represent the … but my time would be wastedWebDec 21, 2024 · Sender/receiver workflows are quite common for threads.
