Detailed Description

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

Input stream that gets its data from a result field.

Use this class exactly as you would any other istream to read data from a field. All formatting and streaming operations of std::istream are supported. What you'll typically want to use, however, is the fieldstream typedef (which defines a basic_fieldstream for char). This is similar to how e.g. std::ifstream relates to std::basic_ifstream.

This class has only been tested for the char type (and its default traits).
