Function

GLiblog_writer_journald

since: 2.50

Declaration [src] 

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

Description [src]

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

Type: GLogLevelFlags

Log level, either from GLogLevelFlags, or a user-defined level.

fields

Type: gsize

Number of elements in the fields array.

user_data

Type: gpointer

User data passed to g_log_set_writer_func().

The argument can be NULL.

Return value
