writer_journald

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 LogWriterFunc.

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

Parameters:

fields	key–value pairs of structured data forming the log message
log_level	log level, either from LogLevelFlags, or a user-defined level
n_fields	number of elements in the fields array
user_data	user data passed to set_writer_func

Returns:

g_log_writer_handled on success, g_log_writer_unhandled otherwise
