## Synopsis

    // In header: <boost/log/sinks/debug_output_backend.hpp>

    template<typename CharT>
    class basic_debug_output_backend :
      public basic_formatted_sink_backend< CharT, concurrent_feeding >
    {
    public:
      // types
      typedef base_type::char_type   char_type;    // Character type.
      typedef base_type::string_type string_type;  // String type to be used as a message text holder.

      // construct/copy/destruct
      basic_debug_output_backend();
      ~basic_debug_output_backend();

      // public member functions
      void consume(record_view const &, string_type const &);
    };

## Description

The sink uses Windows API in order to write log records as debug messages, if the application process is run under debugger. The sink backend also provides a specific filter that allows to check whether the debugger is available and thus elide unnecessary formatting.
