Class template basic_debug_output_backend

boost::log::sinks::basic_debug_output_backend — An implementation of a logging sink backend that outputs to the debugger.

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. 

  // public member functions
  basic_debug_output_backend();
  ~basic_debug_output_backend();
  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.
