std::swap(std::basic_ofstream)

template< class CharT, class Traits > void swap( basic_ofstream<CharT,Traits> &lhs, basic_ofstream<CharT,Traits> &rhs );

Specializes the std::swap algorithm for std::basic_ofstream. Exchanges the state of lhs with that of rhs. Effectively calls lhs.swap(rhs).

lhs, rhs
