nounitbuf


manipulator function
<ios>
ios_base& nounitbuf ( ios_base& str );

Do not force flushes after insertions

Clears the unitbuf "format" flag for the str stream.

When the unitbuf flag is not set, the associated buffer is not forced to be flushed after every insertion operation.

This flag can be set with the unitbuf manipulator, forcing flushes after every insertion.

The unitbuf flag is not set in standard streams on initialization.

Parameters

str
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 Value

A reference to the stream object.

  ofstream outfile ("test.txt");
  outfile << nounitbuf <<  "Test " << "file" << endl;
  outfile.close();
  return 0;
}
