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:
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)
