Detailed Description

template<typename CHAR = char, typename TRAITS = std::char_traits<CHAR>>
class pqxx::basic_olostream< CHAR, TRAITS >

Output stream that writes data back to a large object.

Use this class exactly as you would any other ostream to write data to a large object. All formatting and streaming operations of std::ostream are supported. What you'll typically want to use, however, is the olostream typedef (which defines a basic_olostream for char). This is similar to how e.g. std::ofstream is related to std::basic_ofstream.

Currently only works for <char, std::char_traits<char> >.
