std::filesy...::operator=(3)

okay so bestie, today’s manual page is std::filesy...::operator=(3), straight out of the C++ Standard Libary, and it’s giving “tiny page, assignment operator energy.” let’s get into it. 💖

🎀 NAME 🎀

• std::filesystem::filesystem_error::operator= — that’s the page name, and the NAME line then repeats the exact same string: std::filesystem::filesystem_error::operator=.

✨ Synopsis ✨

here’s the signature exactly as shown:

filesystem_error& operator=( const filesystem_error& other )
(since C++17)
noexcept;

so what does it do? it assigns the contents with those of other. and if *this and other both have dynamic type std::filesystem::filesystem_error, then std::strcmp(what(), other.what()) == 0 after assignment. no cap, that’s the behavior. 🦋

🌸 Parameters 🌸

• other — another filesystem_error object to assign with.

💅 Return value 💅

• *this — yep, it returns *this. iconic.

🔥 Notes 🔥

ngl, here’s the implementation tea the page gives us: typical implementations store path objects referenced by path1() and path2() in a reference-counted storage. as a result, *this and other usually share their path objects after assignment. so yeah, they usually share their path objects after the assignment. 💀

🍓 Example 🍓
