std::exception::operator=(3)

✨ std::exception::operator=(3) ✨

Manual: C++ Standard Libary — yes bestie, that's the exact spelling from the header, and we are respecting it 💅

✨ NAME ✨

std::exception::operator= — that's the name, and the NAME line literally gives you std::exception::operator= - std::exception::operator=. Same name twice, zero notes, iconic. 👑

✨ Synopsis ✨

okay so here are the signatures, and the throw() → noexcept timeline is the vibe check:

exception& operator=( const exception& other ) throw();   (until C++11)
exception& operator=( const exception& other ) noexcept;  (since C++11)

Copy assignment operator. Assigns the contents of other. That's the whole job. 💖

If *this and other both have dynamic type std::exception then std::strcmp(what(), other.what()) == 0 after assignment. no cap, that's the exact condition. 🌸

💖 Parameters 💖

• other — another exception to assign the contents of. That's it. One parameter, fully booked and busy. 💅

🩹 Defect reports 🩹

The following behavior-changing defect reports were applied retroactively to previously published C++ standards. retroactive lore? we love to see it 👑

• DR: LWG 471
• Applied to: C++98
• Behavior as published: the effects of calling what() after assignment are implementation-defined
• Correct behavior: required to be the same as the original what() if the dynamic types are the same

That's the whole page, bestie — source/version/date: http://cppreference.com, 2024.06.10, std::exception::operator=(3). mwah 💋
