unitbuf

Causes output to be processed when the buffer is not empty.

ios_base& unitbuf(
   ios_base& _Str
);

Parameters

• _Str
  A reference to an object of type ios_base, or to a type that inherits from ios_base.

Return Value

A reference to the object from which _Str is derived.

Remarks

Note that endl also flushes the buffer.

nounitbuf is in effect by default.

The manipulator effectively calls _Str.setf(ios_base::unitbuf), and then returns _Str.
