When the unitbuf flag is set, the associated buffer is flushed after each insertion operation.
This flag can be unset with the nounitbuf manipulator, not forcing flushes after every insertion.
The unitbuf flag is not set in standard streams on initialization.
- Stream object where to apply.
Because this function is a manipulator, it is designed to be used alone with no arguments in conjunction with the insertion (<<) and extraction (>>) operations on streams (see example below).
Return ValueA reference to the stream object.
