std::basic_ios::set_rdbuf(3)

🎀 std::basic_ios::set_rdbuf 🎀

okay so bestie, this page is from the C++ Standard Libary and it’s all about std::basic_ios::set_rdbuf. yes, that’s the same name twice in the NAME section—iconic. 💖

🌸 NAME

std::basic_ios::set_rdbuf — literally std::basic_ios::set_rdbuf, no cap. this is the protected stream-buffer setter page. 🫶

✨ Synopsis

it’s giving protected member function, and it’s been here since C++11:

protected:                                                 (since
C++11)
void set_rdbuf( std::basic_streambuf<CharT,Traits>* sb );

so what does it do? it sets the associated stream buffer to sb without clearing the error state. periodt. 💅

and why is it protected? because it’s called by the move constructors of derived streams such as std::basic_ofstream or std::basic_istringstream, as the final step after constructing the base class and after moving the stream buffer: only the most derived stream class knows how to correctly move the stream buffer, but std::basic_ios needs to be made aware of the stream’s new location so that its public member functions can access it. iykyk. ✨

🎀 Parameters

• sb — stream buffer to associate to.

💖 Return value

(none) — literally no return value, bestie.

💅 Exceptions

Throws nothing. clean. no drama. 🌸
