Function

GLiblog_writer_journald

Declaration

GLogWriterOutput
g_log_writer_journald (
  GLogLevelFlags log_level,
  const GLogField* fields,
  gsize n_fields,
  gpointer user_data
)

Description

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 GLogWriterFunc.

If GLib has been compiled without systemd support, this function is still defined, but will always return G_LOG_WRITER_UNHANDLED.

Available since:

2.50

Parameters

`log_level`	`GLogLevelFlags`
	Log level, either from `GLogLevelFlags`, or a user-defined level.
`fields`	An array of `GLogField`
	Key–value pairs of structured data forming the log message.
	The length of the array is specified in the `n_fields` argument.
	The data is owned by the caller of the function.
`n_fields`	`gsize`
	Number of elements in the `fields` array.
`user_data`	`gpointer`
	User data passed to `g_log_set_writer_func()`
	The argument can be `NULL`.
	The data is owned by the caller of the function.

Return value

Returns:	`GLogWriterOutput`
	`G_LOG_WRITER_HANDLED` on success, `G_LOG_WRITER_UNHANDLED` otherwise.
