std::emit_on_flush,std::noemit_on_flush(3) C++ Standard Libary std::emit_on_flush,std::noemit_on_flush(3)

NAME

std::emit_on_flush,std::noemit_on_flush - std::emit_on_flush,std::noemit_on_flush

Synopsis


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

Parameters


os - reference to output stream

Return value


os (reference to the stream after manipulation)
