Constants:

• public const string FILE
• public const int LINE
• public const string METHOD

Methods:

• public bool get_debug_enabled ()
  Return whether debug output from the GLib logging system is enabled.
• public void remove_handler (string? log_domain, uint handler_id)
  Removes the log handler.
• public LogLevelFlags set_always_fatal (LogLevelFlags log_levels)
  Sets the message levels which are always fatal, in any log domain.
• public void set_debug_enabled (bool enabled)
  Enable or disable debug output from the GLib logging system for all domains.
• public void set_default_handler (LogFunc log_func)
  Installs a default log handler which is used if no log handler has been set for the particular log domain and log level combination.
• public LogLevelFlags set_fatal_mask (string log_domain, LogLevelFlags log_levels)
  Sets the log levels which are fatal in the given domain.
• public uint set_handler (string? log_domain, LogLevelFlags log_levels, LogFunc log_func)
  Sets the log handler for a domain and a set of log levels.
• public void set_handler_full (string? log_domain, LogLevelFlags log_levels, owned LogFunc log_func)
  Like set_handler , but takes a destroy notify for the user_data.
• public void set_writer_func (owned LogWriterFunc func)
  Set a writer function which will be called to format and write out each log message.
• public void writer_default_set_use_stderr (bool use_stderr)
  Configure whether the built-in log functions ( default_handler for the old-style API, and both writer_default and writer_standard_streams for the structured API) will output all log messages to `stderr`.
• public bool writer_default_would_drop (LogLevelFlags log_level, string log_domain)
  Check whether writer_default and default_handler would ignore a message with the given domain and level.
• public string writer_format_fields (LogLevelFlags log_levels, LogField[] fields, bool use_color)
  Format a structured log message as a string suitable for outputting to the terminal (or elsewhere).
• public bool writer_is_journald (int output_fd)
  Check whether the given output_fd file descriptor is a connection to the systemd journal, or something else (like a log file or `stdout` or `stderr`).
• public bool writer_supports_color (int output_fd)
  Check whether the given output_fd file descriptor supports ANSI color escape sequences.

Fields:

• public LogFunc default_handler
  The default log handler set up by GLib; set_default_handler allows to install an alternate default log handler.
• public LogWriterFunc writer_default
  Format a structured log message and output it to the default log destination for the platform.
• public LogWriterFunc writer_journald
  Format a structured log message and send it to the systemd journal as a set of key–value pairs.
• public LogWriterFunc writer_standard_streams
  Format a structured log message and print it to either `stdout` or `stderr`, depending on its log level.
