Enables or disables automatic flushing of the output stream after any output operation. Has no effect on input.
1) enables the unitbuf flag in the stream str as if by calling Template:cpp
2) disables the unitbuf flag in the stream str as if by calling Template:cpp
This is an I/O manipulator, it may be called with an expression such as Template:cpp for any out of type Template:cpp or with an expression such as Template:cpp for any in of type Template:cpp.

Notes
Flushing is performed in the destructor of the Template:cpp object, which calls Template:cpp if Template:cpp.
The standard output objects Template:cpp and Template:cpp have their unitbuf bit set by default.
Parameters
| str | - | reference to I/O stream |
Return value
str (reference to the stream after manipulation)
