Function

GLib-2.0 ▶ GLib ▶ log_writer_journald`Since 2.50`

log_writer_journald(
    log_level: LogLevelFlags,
    fields: LogField[],
    user_data?: any,
): LogWriterOutput
Format a structured log message and send it to the systemd journal as a set of key–value pairs.

All fields are sent to the journal, but if a field has length zero (indicating program-specific data) then only its key will be sent.

This is suitable for use as a GLib.LogWriterFunc.

If GLib has been compiled without systemd support, this function is still defined, but will always return GLib.LogWriterOutput.UNHANDLED.
Parameters
- log_level: LogLevelFlags
  log level, either from GLib.LogLevelFlags, or a user-defined level
- fields: LogField[]
  key–value pairs of structured data forming the log message
- Optionaluser_data: any
  user data passed to GLib.log_set_writer_func
Returns LogWriterOutput
GLib.LogWriterOutput.HANDLED on success, GLib.LogWriterOutput.UNHANDLED otherwise
