function template

std::swap (basic_ofstream)

template <class charT, class traits>
  void swap (basic_ofstream<charT,traits>& x, basic_ofstream<charT,traits>& y);

Swap output file streams

Exchanges the values of the basic_ofstream objects x and y.

This is an overload of the generic algorithm swap that behaves as if x.swap(y) was called.

Parameters

x,y: basic_ofstream objects of the same type (i.e., having both the same template parameters, charT and traits).

Return value

none

Example

// swapping ofstream objects
#include <fstream>      // std::ofstream

int main () {
  std::ofstream foo;
  std::ofstream bar ("test.txt");

  swap(foo,bar);

  foo << "lorem ipsum";

  foo.close();

  return 0;
}
