std::emit_o...mit_on_flush(3)

okay so bestie, welcome to std::emit_o...mit_on_flush(3) from the C++ Standard Libary — yes, that's the manual name, spelling and all, and yes, the title is literally std::emit_o...mit_on_flush(3) 💅 This page is giving "two tiny manipulators who control flush behavior" and honestly? iconic.

✨ NAME ✨

std::emit_on_flush,std::noemit_on_flush — the original NAME line is literally std::emit_on_flush,std::noemit_on_flush - std::emit_on_flush,std::noemit_on_flush, so yeah, it says the same thing twice. We love a repetitive queen 💅

🌸 Synopsis 🌸

Defined in header <ostream> 🦋

(1) (since C++20)

template< class CharT, class Traits >
std::basic_ostream<CharT, Traits>& emit_on_flush(
std::basic_ostream<CharT, Traits>& os );

(2) (since C++20)

template< class CharT, class Traits >
std::basic_ostream<CharT, Traits>& noemit_on_flush(
std::basic_ostream<CharT, Traits>& os );

If os.rdbuf() actually points to a std::basic_syncbuf<CharT, Traits, Allocator> buf, these manipulators toggle whether it emits — i.e., transmits data to the underlying stream buffer — when flushed:

1. calls buf.set_emit_on_sync(true)
2. calls buf.set_emit_on_sync(false)

Otherwise, these manipulators have no effect 😌 periodt.

This is an output-only I/O manipulator, it may be called with an expression such as out << std::emit_on_flush for any out of type std::basic_ostream.

🎀 Parameters 🎀

• os — reference to output stream.

💖 Return value 💖

• Returns os (reference to the stream after manipulation) ✨
