Detailed Description

template<typename CHAR = char, typename TRAITS = PGSTD::char_traits<CHAR>>
class pqxx::basic_lostream< CHAR, TRAITS >

Stream that reads and writes a large object.

Use this class exactly as you would a std::iostream to read data from, or write data to a large object. All formatting and streaming operations of std::iostream are supported. What you'll typically want to use, however, is the lostream typedef defined below. This is similar to e.g. std::fstream.

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