Defined in header 
 
 
<ostream> 
 template< class CharT, class Traits >
std::basic_ostream <CharT, Traits>& emit_on_flush( std::basic_ostream <CharT, Traits>& os );
 (1) 
 (since C++20) 
std::basic_ostream <CharT, Traits>& emit_on_flush( std::basic_ostream <CharT, Traits>& os );
template< class CharT, class Traits >
std::basic_ostream <CharT, Traits>& noemit_on_flush( std::basic_ostream <CharT, Traits>& os );
 (2) 
 (since C++20) 
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, toggles 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.
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 .
